chore: input[type=date], the modifier number could converted to a timestamp

[shengxj1]

when an input element with type="date" or "datetime-local", the modifier number converts 2023-07-01T20:00 and 2023-07-01 to 2023, which is a bit odd and would make sense if it could be converted to a timestamp

String(new Date())
> 'Sat Jul 01 2023 22:19:11 GMT+0800 (China Standard Time)'
Number(new Date())
> 1688221156086
