[p4] file modification time in the future causing gmake to loop

[Shawn Hladky]

Perhaps the user in Asia has the incorrect timezone set on their PC.  I have
not seen this problem with modtime and our users in Sri Lanka.  Modtime uses
the timestamp from the PC that submitted the file (not the Perforce server's
timestamp), but it should be converted to GMT.  I actually wish there were
another option, to set the timestamp to the Perforce server's time when the
changelist was submitted.
