We are reading the event log information in our application from using query in windows management service and Java script. The required event log is based on the current system time that we send through the query to fetch the details. We face a problem while fetching a event log of Windows xp and Windows-7 as the actual time the error message logs differs from the system time. Also the time difference is not same in all the machines of same configuration.

Example : Conider an error is logged in windows event log at 05.00 AM but the time logged as 02.00 AM (which can also 07.00 AM or any difference of time) in the event log. Now I was unable to decide the exact time of an error log.

We made a workaround in Windows-7 by fetching it using Record ID which is increasing for every event log but the same does not work in Windows-XP as the record id is not increasing and does not look to have a standard format.

Kindly provide us some solution to fetch the error log information of the particular time.

You need to be considering the fact that 'remote' machines may not be synched correctly or consistently either to a local NTP service or to a remote NTP service, and that the regional time zones for different remote machines may also be different.

You should consider ALSO retrieving the remote UTC values, which are absolute values.

See the following MS page for more information for W7/W2008 etc: as I recall it there are similar WMI calls for XP


If these are all machines on the same LAN - and especially if they are within the same AD - then consider implementing NTP correctly so all systems use only a local server as their RTS source, and then configure that server to synch time with an appropriate external RTS such as pool.ntp.org. Allowing individual machines to synch their NTP with external sources is a recipe for trouble.

You may well find that you can do this task far better and more easily using Powershell. See the following for some examples:



rneuschul has it correct. You need to verify that all the systems have syncronized to a common NTP server or to one of the public NTP servers. Ensure that you have accounted for differences in timezone and DST.
