Hi Chintan,
The time that is set is based on the machine. If the machine time is PST, it's easy to subtract 3 hours to get EST. If your machine times are all different, you will need to write code to access the GMT+0 time and add 5 hours (or whatever it is). We can probably add this to qRules, and you know it might be a good idea. I'll add a feature case....
