This should have been automized by adding a new feature to Kvalobs. The insert of missing values should have used a function to give the correct actual obstime. Information about when to use this function should be kept in obs_pgm. | Pri 0-1 Mar 08 |

Scope
met.no / Per-Ove Kjensli> We have yet decided to awoid this problem by setting the obstime to be fixed 06 UTC throughout the year. We experiece that the obstime are rather miscellanious at the observers site. In reality we speak of a “morning observation” at manual precipitation stations. We will update the obstime to 06 UTC in our Climate DB's for all previous years. The descission is influenced by the fact that in future all stations will use 06 UTC as real obstime.
Task
We terminate the activity after setting fixed obstime 06 UTC for manual precipitation stations reporting data by weekly cards (Kvalobs typeid = 402)
