"toTime" : "2021-10-06T23:59:59.000"

in java . Help please!

CodePudding user response：

Generally speaking, you really want to avoid representing date/time as String where ever possible.

Displaying date/time values to the user should be done in styles that respect their localisation and transmitting date/time values using JSON or XML should use common/standardised formats. This reduces a LOT of issues (don't even get me started)

For example, had I the choice, I would prefer to use ISO_LOCAL_DATE (uuuu-MM-dd) and ISO_LOCAL_DATE_TIME (uuuu-MM-dd'T'HH:mm:ss). I'm already worried about the lack of time zone information
