Back up time stamp?

[dipak_kumar]

Hello team,

Actually i was taking Back up time stamp of ABAP system using DB12 and from OS level , i found that from DBserver time is 21:18 GMt and from SAp gui it is 20:00 gmt , may i know why there is the difference in time stamp but my sap is completely in synchronise with DATABASE server.

Can anyone let me know shall i go for sapnote ?

Hello,

Have you checked if the java applications timestamp is synchronized with the time of the server? I mean, if you connect to the portal, the time is the same as in the server, for example?

The time for the AS Java is defined by the JDK being used, so it is not depending on the abap side of the system.

Hi,

On the SAP side, run transaction /nSTZAC. The system time zone is client independent and uses default time zone (client dependent).

The OS time and SAP system time should be the same.

The tables for time zone customizing are client dependent and therefore it is necessary to change the time zone settings in each client to receive a correct date/time calculation. It is necessary to update the DST rules in all clients including 000.

In terms of Java please check.

You can change the timezone of the JVMs using the -Duser.timezone parameter

So you should add -Duser.timezone=<timezone> to all dispatcher and server processes in your systems, using the configtool

1) open config tool

2) select yes

3) select "cluster-data->instanceXXX->serverXXX/Dispatcher"

4) in "Java parameters" add new line "-Duser.timezone=<timezone>"

5) click "Apply changes"

6) restart your instance

Please refer to following link which gives you the list of

user.timezone supported by JVM 1.4

Supported user.timezone property values for the Development Kit for Java
