如何在 mysql 中单独将此日期转换为 unix 时间戳？
How to convert this date into a unix timestamp in mysql alone?
这是日期：2018-01-25T13:39:40-05:00
来自 API.
到目前为止，我这样做了：SELECT UNIX_TIMESTAMP(STR_TO_DATE('2018-01-25T13:39:40-05:00', '%M %d %Y %h:%i%p')) AS time
但它给了我 NULL。
我认为 -05:00 是时区。但是T是，我不知道。
也许还有另一种方法可以去掉 T 和 -05:00 并将 24 小时转换为 12 小时
您不必使用 STR_TO_DATE 函数。
可以直接使用UNIX_TIMESTAMP。
UNIX_TIMESTAMP() is called with a date argument, it returns the value
of the argument as seconds since '1970-01-01 00:00:00' UTC.
The date argument may be a DATE, DATETIME, or TIMESTAMP string, or a number in YYMMDD, YYMMDDHHMMSS, YYYYMMDD, or YYYYMMDDHHMMSS format.
The server interprets date as a value in the current time zone and converts it to an internal value in UTC. Clients can set their time zone
