interfacing arduino with RTC module and gps

how can i read the date and time from gps module instead of reading it from the system(computer) time i.e., microcontroller connected to.
my project is i want to display date and time on lcd display that i got from my gps. Based on the location it should change. If i move from one location to another (INDIAN STANDARD TIME-AMERICAN TIME).
how can write code my hardware devices are given in the below.

No, they weren't.

Can you read ANY data from the GPS? Can you recognize which sentences contain time data? Do you know which frame of reference the time is in?

Moving the GPS from one area to another will NOT change the time that it returns. You will have to know what time zone is appropriate for where the GPS is, and you will have to convert from the UTC time that the GPS reports to the local time.
