Question

I am using MySQL 5 and I am trying to convert a datetime field to a UTC_TIMESTAMP. Here is what I have but it’s not working and not sure if I could even do this. But could someone please tell me what I am doing wrong? Thanks

I have tried this:

SELECT
UTC_TIMESTAMP(start),
c.login_datetime as `start`
FROM
tbl_employees_login AS c

And This…

SELECT
UTC_TIMESTAMP(c.login_datetime) as `start`
FROM
tbl_employees_login AS c

And neither works!!

Answer 1

Try the UNIX_TIMESTAMP() function insted:

SELECT
  UNIX_TIMESTAMP(c.login_datetime) as `start`
FROM
  tbl_employees_login AS c ;

Beware that:

The server interprets the date (or datetime) as a value in the current time zone and converts it to an internal value in UTC.
