Yes, I looked at it briefly, but it appears ITime can only handle
whole-second precision.

Perhaps it would be possible to modify IDate/ITime to store time as whole
milliseconds, but in the numeric type. This change would allow it to
store any reasonable date/time in milliseconds, but data.table could
still use radix sorting. Thoughts?
