TIMESPLIT functions splits Geo Time Series™ instances based on quiet periods, i.e. periods during which the GTS has no values.
Whenever a quiet period longer than a minimum duration is encountered, the Geo Time Series™ is split.
If input gts has no values or if 'label' is already part of the labels of 'gts', then the resulting list of GTS will only contain a clone of 'gts'. Make sure to test your GTS split size if needed.
