IMHO, all machines acting as servers should by default be running some sort of
time sync program (Windows has an NTP service and *nix boxes can use either some
ntpd variant or better yet clockspeed). There is really no excuse not to make
sure that the system clock on servers is correct; there are readily available
public sources of time sync pretty much everywhere. Clients on networks should
be getting their sync from their local servers (Windows makes this automatic).
Smart users should set up their disconnected client boxes to synchronize with
some external host.

This doesn't have anything to do with Subversion, however. In that case, the
Subversion client should really be using the timestamps as sent by the server
and only changing the TZ offset if necessary. The only time that the Subversion
client should be concerned with local time is when comparing timestamps for
modifications (which happens in the filesystem quite automatically).
