timer.getMilliSecCounter
timer.getMilliSecCounter is a function that is part of the timer functions.
Returns the amount of milliseconds elapsed since last calculator reboot.
In the Computer software emulator, it returns an absolute negative time.
The counter rolls over to zero when it passes 232 milliseconds.
This has been introduced in TI-Nspire OS 3.0 (Changes).

Syntax

(No arguments)
Example
theTime = timer.getMilliSecCounter()
Good to know
In order to define a relative time origin, whether it's on calc or in the emulator, this can be an example :
function now()
local now = timer.getMilliSecCounter()
if now < 0 then
now = now + 2^31
end
return now
end
If you want to do something after 60 seconds, for example, here is what you have to do :
<source>timeleft = 60-math.floor((math.abs(timer.getMilliSecCounter()) - math.abs(startTime))*0.001) -- startTime would be a variable defined earlier as '0', for instance. if math.abs(math.floor(timeleft)) == 0 then
-- your code here --
end
