Date: September 13, 2010 03:29PM David, I wouldn't recommend storing dates/times in anything other than UTC. As soon as you have two rows with different time zones, you add a lot of unnecessary overhead, IMO. You also don't need to submit the time zone info to the database. Just...
在R中读取表示为UTC+offset (no DST)的日期时间,可以使用lubridate包来处理。lubridate是一个用于处理日期和时间的R包,它提供了一系列函数来解析、操作和格式化日期时间数...
该文件的日期时间字段表示为UTC+01 (因此从协调世界时的偏移量为1h，没有DST)。

I am trying to do some date manipulation on UTCDates, without having timezones get in the way. However when doing calculations that span over DST periods, I am finding the output has a1 hour offset due to DST. Starting UTC date: 2025-03-...

David, You can just store dates/times in UTC. Then, in your client, get the UTC offset and add it (or subtract it) from the date/time from the server (UTC). When sending date/time values back to the database, just reverse the math on the client before sending. HTH, Chad...
I finally did run into a killer problem when I realized that for one UTC offset and DST flag there are multiple possible time zones in the TZ database. Meaning I truly can't do the mapping automatically. Therefore I think I will be going with letting the user select "system default" ...
