If the command line switch \fB\-\-defaults\fR is not used or no default mtime
is specified, the value of the environment variable \fBSOURCE\_DATE\_EPOCH\fR
is used for all file and filesystem timestamps.
If \fBSOURCE\_DATE\_EPOCH\fR is not set, not a parsable number or it is out of
range, the timestamps default to 0.
