Returns the elapsed time in milliseconds.

_date_msec rolls over to zero once a day (?), so there will be one time per day that maybe it will return a large, negative number.

[lp_page_timer] returns the elapse time in milliseconds except when first called (default is it returns nothing)

[lp_page_timer: -showfirst] will return zero on the first call instead.

Calling it multiple times will cause it to return elapse seconds between each call.

Note: creates a page-only variable called "lp_page_timer" to store the clock_ticks value.

Parameters

-showfirst

boolean, optional

Will output zero after the first call. Default is to not return a value the first time.

Sample Usage

[lp_page_timer]
[sleep: 50]
[lp_page_timer]
[sleep: 200]
[lp_page_timer]
[sleep: 10]
[lp_page_timer]
