libfaketime intercepts various system calls which programs use to
retrieve the current date and time. It can then report faked dates and times
(as specified by you, the user) to these programs. This means you can modify
the system time a program sees without having to change the time system-wide.
libfaketime allows you to specify both absolute dates (e.g., 01/01/2004) and
relative dates (e.g., 10 days ago).
libfaketime might be used for various purposes, for example
- running legacy software with y2k bugs
- testing software for year-2038 compliance
- debugging time-related issues, such as expired SSL certificates
- running software which ceases to run outside a certain timeframe
- using different system-wide date and time settings, e.g., on OpenVZ-
based virtual machines running on the same host
- deterministic build processes.

# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.
# Line up the first '|' above the ':' following the base package name, and
# the '|' on the right side marks the last column you can put a character in.
# You must make exactly 11 lines for the formatting to be correct. It's also
# customary to leave one space after the ':' except on otherwise blank lines.
