10 Timer Functions

This group of functions covers VSE capability to work with timers, internal routines that repeatedly measure a
timing interval between different events.

10.1 VSE Time Object

A VSE time object presents time intervals in verification scripts. The verification script time object is a
“list” object of two elements.

[seconds, nanoseconds]

Note:

The best way to construct a VSE time object is to use the

Time()

function (see below).
