12AM is an easy way to keep track of world clocks and time zones.
HOW IT WORKS:
Search for a location in menu, and select the time zone you wish. From there, you can edit the name of the zone to add personalized descriptions: friends, colleagues...
Thats it! Now you are able to have your own custom made world clock; on your notification center as well. This way you are never far form the information you need to keep your friends and family close!
