Military Time (aka Zulu time) is the UCT standard. It is essentially identical to "Greenwich Mean Time" except that UCT has 00:00 as Mid-night no matter what. This avoids the confusion where GMT has 00:00 sometimes as mid-day as well.

As it's the same as GMT, it is the time period for most of Britain (except during British Summer Time).

You can change it in the preferences under "Date And Time" to your specific time zone.
