CAUTION
1) Verify that correct time and
date have been input in the
TTY message.
2) Never span the midnight hour
in either direction. An advance
through midnight will inhibit
the midnight routines and no
AMA header will be generated
for the required data change.
A CLK-SET back through the
midnight hour will repeat the
midnight routines and advance
the date a second time.
3) Observe restricted hours.
4) Do not make minor adjustments
between 2300 hours and midnight.
Such changes prevent the proper
billing of all calls affected
by the time change and held
through midnight.
