ZDATE_ILLEGAL_LOCTIME dump in VMWare environment


Hello SAP Experts,

I am getting ZDATE_ILLEGAL_LOCTIME or ZDATE_LARGE_TIME_DIFF short dump in my SAP System which is running on Windows OS in VMware vSphere virtual environment.

The developer traces of the error can be obeserved as follows:

1) ERROR => 24.09.2013 21:58:04.800 PID=4216, TID=3312#SapTimer
error. SapTime differs from Windows time. ERRORS: 0,
SapTime-WindowsUtcTime=-10814 seconds.

2) ERROR => 13.06.2013 01:42:18.693 PID=2840, TID=3920#SapTimer error.
Time may be incorrect on your system. Windows time jumped approx +1788
seconds.  Slept 1014 millisec

    In order to resolve this error use  either w32time or NTP (Network Time Protocol) as the primary time synchronization utility (highly recommended) on the ESX Server Host and follow the recommendations from VMware KB 1318

    It is no longer recommended by VMware to use the time synchronization with their VMware Tools.

    The runtime error you are facing mostly happens in the following situations:

    1) If the local windows time of the application server is inconsistent and varies from SAP time.

    2) if the difference between the local time of the application server and the local time of the database server is huge

    Therefore only time services who change the time gradually are allowed for synchronizing the application server.
