This is primarily for robots to send date and time information to users and have it displayed in local time. The format of the UTC CTCP is:
UTC number
where number is the ASCII representation of the 32 bit
integer representing the time as is used on UNIX machines.
When IRCII receives this CTCP, it replaces the text of
the local time expressed in the local language back into
the original message. Thus if you send the following:
NOTICE nick The time is ^AUTC 702777074^A
The user might see:
-yournick- The time is Thu Apr 9 09:51:14 1992
(if their timezone is Australian Eastern Standard Time).
Obviously you can use the $TIME() function here effectively.
