-----------------------------------------------------------
[~maxgekk] , I have a question regarding the conversion from Spark Time to
Arrow Time and then from Arrow Time back to Spark Time.
Supported time units for Arrow Time Type: SECOND, MILLISECOND, MICROSECOND,
NANOSECOND.
Supported time precisions for Spark Time Type: 0 -> SECOND, 1 -> ?, 2 -> ?, 3:
MILLISECOND, 4 -> ?, 5 -> ?, 6: MICROSECOND.

Do you have any suggestions for managing the precision impact on this
conversion?
