Review Comment:
How many values `long datetime` could be? Seems all of them will be `0`
after `& (0x8000000000L - 1)`, and `0000-00-00 00:00:00` should be only one
value, so I'm not sure whether it's correct or not.
It's better to find related official document and put it here, then we could
discuss about it.

Review Comment:
It's better to add incremental task in E2E to verify related modification
