Wrong archive dates in Online 5.05.UE1

After an Online archive completes, it the displays correct date and time of the current archive, however, lower level archives show the date and time of archives done several weeks ago. tbmonitor->archives shows only the dates of the archives completed several weeks ago. The dates never change even for the archive just competed! The system seems to run ok and tbcheck -cr does not give any errors. I upgraded to this version several months before this _problem_ appeared. BTW: this is the online developement system. We have a runtime system of the same version that does not exhibit the symptom. Needless to say this worries me since I don't if my archives will work should I have to restore the system.
