如何仅在mysql中将此日期转换为unix时间戳？

Question

This is the date: 2018-01-25T13:39:40-05:00
Its from an API.

So far, I did this: SELECT UNIX_TIMESTAMP(STR_TO_DATE('2018-01-25T13:39:40-05:00', '%M %d %Y %h:%i%p')) AS time

But its giving me NULL .
I think -05:00 is timezone. But T is, I don't know.

Maybe perhaps there is another way take out T and -05:00 and convert 24hrs to 12hrs

You don't have to use the STR_TO_DATE function.

You can directly use 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

SELECT UNIX_TIMESTAMP('2018-01-25T13:39:40-05:00') AS time
