Change Time Zones

[Former Member]

Hi,

After configured SAPConnect for SMTP mail, we found the date time for sent out message is incorrect (time added 7 hrs). The problem should be incorrect time zone specified in the system. The system time zone is CET (which should be the default) and our local time zone should be UTC+8.

What is the impact on modify the time zone? The system has been up and run for many years. Will the timestamp of the change document became incorrect afterward. All end users and application servers are on the same time zone (UTC+8).

Regards,

Michael

Hi

Please find below details, to understand the current settings and precations, procedure to change the timezone.

1.Navigate to transaction SPRO.

2.Select SAP Reference IMG.

3.Expand Implementation Guide for R/3 Customizing (IMG)  General Settings  Time Zones.

4.Choose u201CMaintain time zone activation in clientu201D.

5.Choose u201CYu201D on the time zone change warning screen.

SAP ABAP engines contain areas for both configuration and maintenance of time zones. The configuration data for time zones is maintained through the application and stored in the database. Changes to the time zone start and finish. Application time is sourced from system time on the OS.

Thanks for the reply.

Actually how to change the system time zone is not the problem. What I worry is "Will this affect the data already stored in the system". Following is the output of TZCUSTHELP.

Hi,

Upon changing the time zone, you go to recycle your SAP to take effect the changes.

When you recycle your SID, it basically gets sync up with the changes made at OS level as well SAP Application level.

As per my knoweldge, it's guranteed for afterwards transactional data but not the already committed data.

I hope it make sense to you.
