Description: Allow the build timestamp to be externally set
|
|
In order to make Ghostscript output reproducible, we need a way to
|
|
set the build timestamp to other values than the current time.
|
|
We now consistently use gp_get_realtime() instead of directly calling
|
|
time() or gp_get_usertime() and make gp_get_realtime() use the value
|
|
found in the SOURCE_DATE_EPOCH environment variable if set. Also,
|
|
environment timezone is fixed to UTC if SOURCE_DATE_EPOCH is used to
|
|
avoid variations.
