Yeah, fair enough, however, I feel I should clarify what I meant.
Currently mIRC will output a text line (in a query, or channel window) like this:
[timestamp] <yournick> remote text
[timestamp] *<nick> action event
[timestamp] is optional.
You can change the format of the timestamp using this:
/timestamp -f [customformat]
By a "themestamp", I was indicating that this could be used to change the output of text within a channel and or query window.
example:
/themestamp -ecqf <customformat>
/actionstamp -ecqf <customformat>
the options are simple:
-e all windows (this is assumed, like global timestamping is, when /timestamp is used)
-q query window only
-c channel window only
-f format - not using this will return the themestamp/actionstamp to the default state.
