Parameterization of timestamp in timezone different that system timezone

Hi All,

I am using Loadrunner 12.53. In my recorded script, there is a timestamp (in  Thu, 24 Nov 2016 08:36:55 GMT format) with every request sent to the the server. But my local machine is with IST timezone. 

Is there any way I can paramterize the timestamp so that is sends the request with a GMT timestamp?

The solution i could figure out was to create a date/time timestamp with "%a, %d %b %Y %H:%M:%S" format and replace all occurences with the parameter. But since the parameter reflects system current date/time therefore the request would send a GMT timestamp.

Thanks,

Rachit
