Closes #5300.
Allows the
pl.DATETIME_DTYPESgroup to cover all timeunit/timezone combinations.Further enhances the
cs.datetimeselector so that it can handle arbitrary permutations of timeunit/timezone, eg:cs.datetime()→ any timeunit, any (or no) timezonecs.datetime( time_zone="*" )→ any timeunit, any timezone (but must have a timezone)cs.datetime( time_zone=None )→ any timeunit, no timezonecs.datetime( ["ms","ns"], time_zone="UTC" )→ any col with UTC timezone and ns or ms precisioncs.datetime( time_zone=["UTC","Asia/Tokyo","Europe/London"] )→ any timeunit, one of the given timezones(Note: all of the expressions above could also be negated using
~).Finally adds the missing piece to the Datetime dtype selection puzzle that has been timezones... :)
