test/zones.rc: Fix instability, read current time once.
The test just called date twice assuming they all
execute in the same second. This causes false positives
with the following errors (usually just 1 second
difference):

The fix is to get the current time once, with date -n
and then pass that to date to format the time and
then concert back and compare.
