Is it possible to display date/time of current user in his/her profile page. It should be base on his/her time zone settings. How can I achieve this goal?
You can modify the user pages (view/edit/etc) with the user templates, like the user profile template In the template's top documentation there's some good info like:
* Use render($user_profile) to print all profile items, or print a subset * such as render($user_profile['user_picture']). Always call * render($user_profile) at the end in order to print all remaining items.
So you can first dpm the $user_profile array and find out the user's timezone, then add php code after the
print render($user_profile); to print the date/time according to the timezone value you retrieved from the user profile array.
