This is the key.  What in fact is happening is that it is leaving
out the timezone, or rather, using an empty timezone name (compare the
output on a Unix system).

Only when the record is modified, then it is rebuilt using just a
single space separator.  Thus, when $3 is reassigned, the record
is rebuilt.

Gawk uses the system's strftime, if there is one, so this isn't suprising.

Here is a workaround for the test that should allow things to work
on cygwin.  I don't have access to such right now, so I can't test it,
but this fix continues to work on my Linux system.  This applies
to test/Makefile.in in the gawk dist.

In the meantime, it'd be good if the Cygnus folks can get their
code to return a timezone name.

Enjoy,

Arnold Robbins
