In theory, RCS takes into account the timezone.  It is suppose to store
the actual times in GMT and translate the times based on the TZ
variable.  Your RCS may vary on this...

This has been noted for RCS.  Perhaps GNU-RCS will have a solution which
may not be completely backward compatible (i.e. expand the year field).

1999 is going to affect a lot of software.  Computer companies should start
planning now for the pain...
