# libfaketime fixes non-determinism related to timestamps ignoring FORCE_SOURCE_DATE

# note that calling faketime and fmtutil is fragile (faketime uses LD_PRELOAD, fmtutil calls /bin/sh, causing potential glibc issues on non-NixOS)
# so we patch fmtutil to use faketime, rather than calling faketime fmtutil
