How to sync time zone between system when SAP PI is the middleware

Hi Experts,

Is there any way to sync the  time zone between systems when sap pi is the middle ware.

Like an example:

when there is flow like ECC==>PI==>OTM.

so in the above case the SAP ECC system follows the UK time  zone, so it will process the message in UK time.

and SAP PI is in America so it will receive the message and process in US time zone and send it to Target system.

and the target system is in another time zone.

So how to sync these time zone in a effective that so that we can say the exact time of flow from End to End.
