Change from Summer to Wintertime / Timestamps

  • Hello,

    does the change from Summer to Wintertime influence the Timestamps in the

    Cluster and Transaction Logs of an Windows 2000 SQL2000 Cluster. In Europe,

    we will have the Same Hour two times.

    Regards

    Rainer

  • Timestamps (datatype) are not related to hours and dates, rather, they are incremental trackers for the transaction logs.

    The datetime fields you have may indeed get duplicates when the times change. Not sure how to handle this as technically, there are 2 11:10s on that day (or whatever the time is).

  • I've got the Question from a Customer, who is in sorrow that his Transaction Logs get double Timestamps and will not be able to recover. I don't know which time SQL-Server uses internally for the logfiles.

  • What type of timestamp is it. SQL stores most all date time values as an integer in the background. The presentation layer converts to the local time zone based on the OS settings. He should not have two timestamps under any condition where the time change would affect it. Now if you are talking about inside msdb sysbackup tables or on the list they should remain in order as they also have an ID value associated with them and not just time.
