It's not all good news though. When new deltas are created with the
delta command, cssc must consult the operating system to
find the current date and time. Some operating systems have a limited
range of date representation. For example, the development system I use
for most of the work on cssc can't report any date later than
Tuesday Jan 19 03:14:07 2038 as the current time. When running on such
systems, cssc will still be able to work with sccs files
containing dates after this, but activities involving the current time
will not work correctly.
This date breakdown occurs most obviously with the date stamp that the
delta program gives each delta in the sccs file, but also
with the commentary-change message of cdc and the default comment
produced by admin when an sccs file is created.
