I know this can be done using extensions (hence http://killzonekid.com/arma-extension-real_date-dll-v3-0/) ... but it's such a simple operation, that it seems weird there is no built-in command for it.
Ideally the command should give you the OS date/time of the machine where it was run (client or server).
The good news is that there is such command already https://community.bistudio.com/wiki/missionStart
The bad news is that it is broken
I see, thanks for the reference. I guess then If I want the current real-time, I would do something like:
missionStart + diag_tickTime
(obviously doing the correct date-math)
However, since for this ticket I am asking for a command the get the current time, it would be nicer if there was something like:
diag_epochTime
that would return the number of seconds since epoch.
