Change the default contact form time in the theme point finder

Hi everyone,
I have questions to ask for help.
I want to change the %% datetime %% time in the Mail System Config in theme Point Finder from UTC to GMT in my local time that I have not done yet.
I need help from everyone.

You should ask the author of the theme but you have no buyer badge on this acocunt and will need to login using the account which purchased the theme or have the purchase code so that the author can verify your file.
