%description
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.

# Upstream libfaketime requires a mess of different compile time flags for different glibc versions and architectures.

# Goal is to build time autodetect these with autotools in the next release ...
