Now let us see the following method to calculate the time difference (in seconds) between two timestamps.
The following is a query to calculate the difference between two timestamps.
mysql> SELECT TIMESTAMPDIFF(SECOND, '2018-10-17 11:51:55', '2018-10-17 11:51:58');
The following is the output in seconds.
+---------------------------------------------------------------------+ | TIMESTAMPDIFF(SECOND, '2018-10-17 11:51:55', '2018-10-17 11:51:58') | +---------------------------------------------------------------------+ | 3 | +---------------------------------------------------------------------+ 1 row in set (0.00 sec)
The following is a query to calculate the difference between two timestamps with the help of UNIX Timestamp.
mysql> SELECT UNIX_TIMESTAMP('2018-10-17 11:57:50') - UNIX_TIMESTAMP('2018-10-17 11:57:45') as DifferenceInSeconds;
The following is the output in seconds.
+---------------------+ | DifferenceInSeconds | +---------------------+ | 5 | +---------------------+ 1 row in set (0.00 sec)
