Description

time64('ns') should support:

• hour
• minute
• second
• millisecond
• microsecond
• nanosecond
• subsecond

time64('us'), time32('ms'), and time32('s') should support those values that fit their resolution.

It's probably debatable if something like millisecond(time32('s')) should be supported but for ease of use it would probably be simplest to just hard code these to return 0.
