  1. Hi, I've got a table with waypoints in my db (called points), these waypoints combine to a route due to the the timestamp in the start and stop column. Now I would like to change the date and/or date + hour to use the track on a different date or start at a differnt hour. But i also would like to keep the intervals between the records. ID Name Lat Lon Start Stop 526 Waypoint X 52.14722000 6.39720000 2020-03-30 20:37:32.0 2020-03-30 20:47:32.0 527 Waypoint Y 52.14670000 6.39139000 2020-03-30 20:47:32.0 2020-03-30 20:52:32.0 528 Waypoint Z 52.14248000 6.39125000 2020-03-30 20:52:32.0 2020-03-30 20:57:32.0 529 Waypoint X 52.14722000 6.39720000 2020-03-30 20:57:32.0 2020-03-30 21:02:32.0 530 Waypoint Y 52.14670000 6.39139000 2020-03-30 21:02:32.0 2020-03-30 21:07:32.0 531 Waypoint Z 52.14248000 6.39125000 2020-03-30 21:07:32.0 2020-03-30 21:12:32.0 532 Waypoint X 52.14722000 6.39720000 2020-03-30 21:12:32.0 2020-03-30 21:17:32.0 533 Waypoint Y 52.14670000 6.39139000 2020-03-30 21:17:32.0 2020-03-30 21:22:32.0 534 Waypoint Z 52.14248000 6.39125000 2020-03-30 21:22:32.0 2020-03-30 21:27:32.0 535 Waypoint X 52.14722000 6.39720000 2020-03-30 21:27:32.0 2020-03-30 21:32:32.0 536 Waypoint Y 52.14670000 6.39139000 2020-03-30 21:32:32.0 2020-03-30 21:37:32.0 Is it possible to use an update querey to change only a part of a datetime stamp? See the colored examples shown below. 2020-03-30 20:37:32.0 2020-03-30 20:37:32.0 Thanks in advance for your help. Arjan
