This is still not quite right on systems with TAI clocks.  With
unpatched 5.1.1, I get:

out exp differ: char 16, line 1
1c1

FAIL: relative

The problem is that this command:
  touch --date='2004-01-16 05:26:38 +0' f || framework_failure=1
uses an offset of 0 from UTC, but it still handles leap seconds
according to the system time zone (right/US/Eastern).  But this
command:
  TZ=utc command ls -og --time-style=+%Y-%m-%dT%H:%M:%S f > out.1 || fail
overrides the system time zone entirely, and thus handles leap seconds
differently.  To ensure that they match, either both commands should
override the time zone, or both should merely specify the UTC offset.
