LASTTICK
gtsThe LASTTICK
function pushes on the stack the newest tick of the Geo Time Series™ on top of the stack or, if the GTS is bucketized, its last bucket.
When applied to a list of GTS, LASTTICK
will return the greatest last tick found across all Geo Time Series™.
If the GTS does not have values, Long.MIN_VALUE
is pushed.
