dotNet uses 0001-01-01 00:00:00.0000000 as the epoch and integer increment is hundredths of a microsecond since the epoch. This makes the largest dotNet timevalue 3155064480000000000 which is a bit more than a third of Int64.MaxValue. The maximum seconds increment of the unix epoch is 253370851200 after which you will need 5 digits for the year, and the minimum value is -62135596800, the next second below which is 0001/12/31 23:59:59.000000 BC.
