Query regarding wtmp log

[Chinnakka K Batakurki <chinnakka.batakurki@in.ibm.com>]

wtmp man page says: the pair of terminal names |/} logs the old/new system
time when date(1) changes  it.
When I change the date/time, it is not logging the record to /var/log/wtmp.

could you please let me know if there is any settings to be done to log the
date change records, when user changes the date/time.

records are entered only when I run the below commands:
 writetmp oldtime
writetmp newtime

Please let me know if there is any other settings other than manually
writing as above


Thanks a lot!
