DB Upgrade to 1.36.34 fails when Monitor_Status contains rows.

[pHr34kY]

Environment:

• ZoneMinder: v1.36.35-noble1
• OS: Ubuntu 24.04.1 LTS x64
• Installed via apt ppa (https://ppa.launchpadcontent.net/iconnor/zoneminder-1.36/ubuntu/ noble main)

Bug description: When upgrading the from the Ubuntu repo version (also v1.36), the database schema upgrade will fail with this error:

ERROR 1292 (22007): Incorrect datetime value: '0000-00-00 00:00:00' for column 'UpdatedOn' at row 1

The problem is that the schema upgrade cannot add a "NOT NULL" column on a table which already has rows. The schema upgrade succeeds if you manually execute TRUNCATE TABLE Monitor_Status; prior to the schema upgrade. The rows are regenerated without issue when zoneminder restarts.

Steps to reproduce:

1. Ensure the Monitor_Status table has rows:

mysql> select * FROM `Monitor_Status` LIMIT 10;
+-----------+------------+------------+-------------+------------------+
| MonitorId | Status     | CaptureFPS | AnalysisFPS | CaptureBandwidth |
+-----------+------------+------------+-------------+------------------+
|         1 | Connected  |      19.99 |        0.00 |           757374 |
|         3 | NotRunning |       0.00 |        0.00 |           163170 |
+-----------+------------+------------+-------------+------------------+
2 rows in set (0.00 sec)

2. Attempt to upgrade from the PPA (sudo apt install zm or sudo apt -f install to repeat the error)
3. Alternatively, manually run the zm_update-1.36.34.sql upgrade script.

Expected behavior The DB schema upgrade should add the UpdatedOn date column and complete without error.

So tired of mysql. Thanks for the report. Going to have to do a 1.36.36 fairly soon.
