Trying a new 7.1.2 installation when running gmake check I get a failure at the abstime test. The regression.diffs file
containsthe following:

Yes. When that regression test was written, July 20, 2001 was far in the
future, and there was concern about Y2K issues etc. There is an explicit
test for dates before a time on or around that date, and "current"
suddenly no longer passes that test!

No problem with your installation, and this is already fixed in current
sources.

btw, we are likely to drop support for "current" in the date/time types
in the next release for several reasons, not the least of which is that
it is a little- or never-used feature.

Nothing.  If you look closely, the abstime test is comparing 'current'
against '30 June 2001'.  This Y2K+18months bogosity escaped notice until
this month :-(
