+Setting FAKETIME by means of a file timestamp
+---------------------------------------------
+
+Based on a proposal by Hitoshi Harada (umitanuki), the "start at" time can now be
+set through any file in the file system by setting the FAKETIME environment variable
+to "%" (a percent sign) and FAKETIME_FOLLOW_FILE to the name of the file whose
+modification timestamp shall be used as source for the "start at" time.
+
+Usage example:
+
+# create any file with December 24th, 2009, 12:34:56 as timestamp
+touch -t 0912241234.56 /tmp/my-demo-file.tmp
+
+# run a bash shell with an endless loop printing the current time
+LD_PRELOAD=/path/to/libfaketime.so.1 \
+  FAKETIME='%' FAKETIME_FOLLOW_FILE=/tmp/my-demo-file.tmp \
+  FAKETIME_DONT_RESET=1 \
+  bash -c 'while true ; do date ; sleep 1 ; done'
+
+# now, while the above is running, change the file's timestamp
+# (in a different terminal window or whatever)
+touch -t 2002290123.45 /tmp/my-demo-file.tmp
+
+
+Changing the 'x' modifier during run-time
+-----------------------------------------
+
+Using FAKETIME_TIMESTAMP_FILE allows for easily changing the FAKETIME setting
+while a program is running:
+
+echo "+0 x1" > /tmp/my-faketime.rc
+LD_PRELOAD=libfaketime.so.1 FAKETIME_TIMESTAMP_FILE="/tmp/my-faketime.rc" \
+  FAKETIME_NO_CACHE=1 ./some-program &
+sleep 10 ; echo "+0 x10" > /tmp/my-faketime.rc
+
+Changing the speed of the wall clock time, i.e., using a different 'x' modifier
+during run-time, by default can lead to greater jumps that may confuse the
+program. For example, if the program has been running for 10 seconds on 'x1',
+and then the setting is changed to 'x10', the faked time will look to the
+program as if it has been running for more than 100 instead of just more than
+10 seconds.
+
+By setting the environment variable FAKETIME_XRESET to any value, transitions
+between different 'x' modifier values will be significantly smoothed:
+
+LD_PRELOAD=libfaketime.so.1 FAKETIME_TIMESTAMP_FILE="/tmp/my-faketime.rc" \
+  FAKETIME_NO_CACHE=1 FAKETIME_XRESET=1 ./some-program &
+
+Setting FAKETIME_XRESET ensures that wall clock time begins to run faster
+only after the 'x' modifier has been changed (when increasing it) and also
+ensures that the reported faked time does not jump back to past values
+(when decreasing it).
+
+Please note that FAKETIME_XRESET internally works by resetting libfaketime's
+internal time-keeping data structures, which may have side effects on reported
+file timestamps. Using FAKETIME_XRESET should be considered experimental at
+the moment.
+
+
+Cleaning up shared memory
+-------------------------
+
+libfaketime uses semaphores and shared memory on platforms that support it in
+order to sync faketime settings across parent-child processes. It will clean
+up when it exits properly. However, when processes are terminated (e.g., by
+Ctrl-C on command line), shared memory cannot be cleaned up properly. In such
+cases, you should occasionally delete
+
+  /dev/shm/faketime_shm_* and
+  /dev/shm/sem.faketime_sem_*
+
+manually (or properly automated). Leftover files there from processes that
+already have been terminated are not a problem in general, but result in a
+libfaketime error the next time a process is started with a process id for
+which such a stale semaphore/shared memory exists. Thus, if you run across
+the following error message
+
+  libfaketime: In ft_shm_create(), shm_open failed: File exists
+
+please cleanup /dev/shm as described above. This is especially relevant
+for long-running systems (servers with high uptime) and systems on which
+a lot of processes are started (e.g., servers handling many containers
+or similar virtualization mechanisms).
+
+
+Intercepting time-setting calls
+-------------------------------
+
+libfaketime can be compiled with the CFLAG "-DFAKE_SETTIME" in order
+to also intercept time-setting functions, i.e., clock_settime(),
+settimeofday(), and adjtime(). Instead of passing the timestamp a
+program sets through to the system, only the FAKETIME environment
+variable will be adjusted accordingly.
+
+

+through github.com/wolfcw/libfaketime, but usually it is also safe (i.e.,
+stable) to use the latest HEAD of the master branch, which contains bug
+fixes since the last tagged release.
+
+You may want to familiarize yourself with the options you can set into
+src/Makefile, but sane defaults for stable operations have been chosen.
+
+Currently, libfaketime does not use autotools yet, so there is
+_no_ ./configure step, but "make" and "make test" will work as expected.
+
+
+However, one problem makes it somewhat difficult to get libfaketime
+working on different platforms:
+
+libfaketime currently has the challenge that depending on the version
+of glibc and the platform (e.g., x86_64 or aarch64) certain compiler
+CFLAGS have to be set manually, as we have not yet found a way to
+safely determine behavior at run-time automatically.
+
+Please proceed as follows:
+
+- run "make test". If everything runs through smoothly and you do not
+  encounter any hangs or test failure reports, use the binaries as
+  they are.
+
+- If you encounter endless hangs during the CLOCK_REALTIME test,
+  add -DFORCE_PTHREAD_NONVER to the CFLAGS.
+
+- If you encounter endless hangs during the CLOCK_MONOTONIC test,
+  add -DFORCE_MONOTONIC_FIX to the CFLAGS. If it works with that,
+  it's fine, otherwise additionally use -DFORCE_PTHREAD_NONVER.
+
+CFLAGS can also be passed through the FAKETIME_COMPILE_CFLAGS environment
+variable, so for example
+
+  FAKETIME_COMPILE_CFLAGS="-DFORCE_PTHREAD_NONVER" make test
+
+would create the libfaketime binaries and run the tests with the
+FORCE_PTHREAD_NONVER flag set in a single step. Likewise there is
+FAKETIME_LINK_FLAGS.
+
+Please do not use FORCE_MONOTONIC_FIX by default, as it would result
+in incorrect operations on platforms that do not need it.
+
+Our observations with a limited number of Linux distributions is that
+libfaketime may require different compile flags per platform even
+if the same distribution and glibc version is used across these
+platforms.
+
+As soon as we have found a reliable way to automatically choose the
+correct compile-time flags, we will remove this burden from you as
+packager for obvious reasons. Until then, please feel free to report
+your experiences with different platforms and distribution versions
+through the issue tracker on Github.
+
+Again, thanks for your time and effort to make libfaketime available
+easily for everyone else!

-Open issues / next steps for libfaketime development
+Open issues / next steps for libfaketime development:
+
+Please see the issue tracker on Github - https://github.com/wolfcw/libfaketime
+
+- New features, such as additional system calls to intercept, are labelled
+  "feature request" when they are considered for implementation
+
+- Issues labelled "help wanted" should be your starting point if you are
+  interested in contributing to libfaketime
+
+Besides the open issues, two major changes are planned for the next release:
+
+- integrate manchicken's autoconf/automake support to get rid of separate Makefile.OSX
 
-- add more functional tests that check more than the basic functionality
 - use the testing framework to also implement unit tests
-- fake timer_create and friends
-- work around thread local storage issue, e.g., by using pthreads
-- add autoconf/automake support to get rid of separate Makefile.OSX
-- improve pthread support

-
-Attached patch works for me, but it is very very dirty.
-
-Possibly side effects.
-
-Alternative seems to be to protect the call to real_clock_gettime so it is
-executed just once (to validate the parameters). Subsequent calls are not
-needed (parameters have been validated).

-Description: Modify system time for single applications
-
-DescDetail: <<
-libfaketime is a library that is dynamically linked to applications
-or system commands at run-time by using the DYLD_INSERT_LIBRARIES
-mechanism. It then intercepts various system calls, which programs
-use to retrieve the current date and time. libfaketime can then
-report faked dates and times to these programs. This means you can
-modify the system time a program uses without having to change the
-date and time system-wide.
-<<
-
-DescUsage: <<
-libfaketime includes a simple wrapper called faketime. Run the
-command faketime without any parameters for usage information.
-For information on how to use libfaketime without the wrapper
-and access its full raw functionality, please see

-# Packaging for OS X
-
-Several software tools assist with the installation of open source software
-on OS X. The authors of libfaketime maintain the libfaketime build spec files
-for MacPorts, Homebrew, and Fink.
-
-
-## MacPorts
-
-Installing libfaketime via MacPorts is based on the provided Portfile, which
-has been included in the official MacPorts distribution since October, 2013.
-Users therefore can use "sudo port install libfaketime" as installation
-command.
-
-Some libfaketime Portfile caveats:
-
-- Github-based source file distribution
-- Non-clang-compilers need to be blacklisted
-- MacPorts folks have requested to avoid a platform-specific Makefile.OSX in
-  the future
-
-Portfile submission is documented in https://www.macports.org/guide/#project.contributing
-and handled via a ticketing system:
-
-- https://trac.macports.org/ticket/40662
-- https://trac.macports.org/ticket/40748
-
-
-## Homebrew
-
-The libfaketime 'formula' for Homebrew is available since November, 2013.
-Homebrew users can use 'brew install libfaketime' as installation command.
-
-Some libfaketime formula caveats:
-
-- "depends_on :macos => :lion" must be set for libfaketime >=0.9.5
-- :llvm builds <= 2336 must be blacklisted because libfaketime =0.9.5
-  requires a compiler with thread local storage support.
-
-Formula submission is handled via pull request on Github following the
-"one formula per commit, one commit per formula" rule, which necessitates
-squashing commits and forced pushes when applying fixes. Style issues
-complementary to the documentation have been discussed in
-
-    https://github.com/mxcl/homebrew/pull/23245
-
-
-## Fink
-
-A libfaketime.info file is included in the Fink 10.7 tree since October,
-2013, and installed using
-
-    fink install libfaketime
-
-Some libfaketime fink info file caveats:
-
-- The dynamic library must be declared as private Shlib; this also necessitates
-  BuildDepends: fink (>= 0.28)
-- "Distribution: 10.7, 10.8, 10.9" is required because libfaketime >=0.9.5 does
-  not work on OS X 10.6 or before anymore.
-- When compiling, PREFIX=%{p} needs to be used because this path is hardcoded
-  into the wrapper. However, "make install" needs to deploy into PREFIX=%{i} to
-  make packaging work.
-
-Submission is via https://sourceforge.net/p/fink/package-submissions/

-# libfaketime packaging
-
-Not everyone feels comfortable with installing tools and libraries manually
-by downloading and building them from source. Luckily enough, voluntary
-maintainers prepare new libfaketime releases for various platforms and make
-them available as binary packages or otherwise automatically installable
-software.
-
-In this directory, we collect build specification files for the platforms
-that we are aware of being actively supported. They help us to analyze
-build issues, create awareness for platform-specific patches that had to
-be applied and might be merged with our code, and provide the contact
-information for future "early release warnings".
