描述

CrateDB does not support storage for timetz, all times have to be stored either in a timestamp or timestamptz.

TimeField only takes the time part of a timestamp, CrateDB trips if we try to do:

TimeField(datetime.datetime.now().time().isoformat())
# SQLParseException[Cannot cast value `22:43:10.001021` to type `timestamp without time zone`]

Because CrateDB needs the full timestmap.

But if we pass a timestamp, the validator of the field trips with: django.core.exceptions.ValidationError: ['“2020-01-01T22:43:10.001021” value has an invalid format. It must be in HH:MM[:ss[.uuuuuu]] format.']

To fix this we should modify the validator of cratedb.fields.TimeField
