unfortunately ant as deployed on the baseline has a bug and expects
SOURCE_DATE_EPOCH to be in milliseconds, and if set in an environment
variable would also override the ant.tstamp.now property even when
explicitly provided at the commandline, so to avoid bogus timestamps
unset it if it was exported in the environment (default build doesn't
export it, but the user may export it to override or provide a value
e.g. when not building from source.
for ant.tstamp.now to work for setting the tstamp value, ant 1.10.2 or
later is required
