2045258 - Errorlog / getdate() shows time jumping (incorrect system datetime / time zone), gets reset sometime later - SAP ASE

Symptom

  • Under the following conditions, the ASE log may show inconsistent time stamps that jump ahead by several hours and then return to the proper time:
    • ASE 15.7 on Solaris 10.x prior to update 11 (Generic_147441-23).
    • ASE running in kernel threaded mode.

  • Under these conditions, the ASE error log may show occaisional timestamps that "jump ahead". That is, the error log timestamp increases by several hours for a period of time and then returns to the proper time. For example, the timestamp of 11:02 may jump to 17:30 and then return to 12:38, as shown below:
