- Linux Mint is a free and open source operating system (OS) distribution based on Ubuntu and Debian for use on x-86 x-64-compatible machines.
During British Summer Time (BST), civil time in the United Kingdom is advanced one hour forward of Greenwich Mean Time (GMT) (in effect, changing the time zone from UTC+0 to UTC+1), so that evenings have more daylight and mornings have less.
The term Central Time (CT) is often used to denote the local time in areas observing either Central Daylight Time (CDT) or Central Standard Time (CST). Central Standard Time is 6 hours behind Coordinated Universal Time (UTC). Central Daylight Time is 5 hours behind UTC. In locations observing Daylight Saving Time (DST) during part of the year, Central Time is not static but switches between CDT and CST. See full time zone map.
