##UTC##
[Wikipedia 2014-10-02] Coordinated Universal Time. The primary time standard by which the world regulates clocks and time. It is one of several closely related successors to Greenwich Mean Time (GMT). For most purposes, UTC is used interchangeably with GMT, but GMT is no longer precisely defined by the scientific community; also, some assert GMT can refer to British Summer Time (BST), which is one hour ahead of UTC.
