According to the documentation:

Template:function=GetInfo GetInfo

The documentation for the GetInfo script function is available online. It is also in the MUSHclient help file.



Quote:

232 - High-performance counter output (in seconds) (double)


That tells you that you will get a double returned (floating-point number) and that it will represent seconds.

The number of seconds is (I think) from when the PC booted, it is not anything to do with the current date or time.

It is intended for doing precise timing.

If you are using Lua you can get the exact same thing from utils.timer:

http://www.gammon.com.au/scripts/doc.php?lua=utils.timer


Example use:


start = utils.timer ()

-- OR

start = GetInfo (232)

-- do something here, like work out how to escape a maze

finish = utils.timer ()

-- OR

finish = GetInfo (232)

time_taken = finish - start  -- in seconds and fractions of a second


The intention is really for debugging scripts, for example you might wonder if one complex regular expression is faster than lots of simple ones, or if LPEG is faster than a regular expression.
