After system reboot, a time inconsistency occurs. The following error messages are recorded in the dstatm log file:


Error *** Unresolvable clock skew detected *** (last run 1066262400, today 1280707200)
Error Main stopped



System time on the Management Centre does not match with the time of the last statistics collection. Reset the timestamp in the header of the dstatm.db file.

Check actual value, key and filename.

    showdb /phion0/dstatm/dstatm.db
    _header_ 2611 100 1053043200 1066262400 manc
    shofw.... box F range clean idle 0 1066276850 data collect


Set the new parameter to the database.
    setbdb _header_ "2611 100 0 0 manc" ./dstatm.db 2611 100 = key
    0 0 manc = value
    ./dstatm.db = filename

Check the new parameter in the database

    showdb /phion0/dstatm/dstatm.db
    _header_ 2611 100 0 0 manc
    fw.... box F range clean idle 0 1066276850 data collect
