MySQL's ADDTIME(~) method adds the specified time interval to a time or datetime value.

Parameters

1. expr1 | time/datetime

The time or datetime to add the time interval to.

2. expr2 | time

The time interval to add to expr1.

Return value

The result of adding the specified time interval to expr1.

Examples

Basic usage

To add a time to a datetime:

SELECT ADDTIME('2019-12-31 23:59:59.999999', '1:1:1.000002');
+-------------------------------------------------------+
| ADDTIME('2019-12-31 23:59:59.999999', '1:1:1.000002') |
+-------------------------------------------------------+
| 2020-01-01 01:01:01.000001 |
+-------------------------------------------------------+

To add a time to a time:

SELECT ADDTIME('12:30:30.999999', '1:1:1.000002');
+--------------------------------------------+
| ADDTIME('12:30:30.999999', '1:1:1.000002') |
+--------------------------------------------+
| 13:31:32.000001 |
+--------------------------------------------+

Negative time

To add negative time (i.e. subtract a time):

SELECT ADDTIME('12:30:30.999999', '-1:1:1.000002');
+---------------------------------------------+
| ADDTIME('12:30:30.999999', '-1:1:1.000002') |
+---------------------------------------------+
| 11:29:29.999997 |
+---------------------------------------------+

Note that there is a separate method SUBTIME(~) specifically for subtracting time intervals from a time / datetime.
