Within the world of Avalon time advances more quickly than it does in so-called 'real-life'. Here, one Avalon day is approximately one 'real-life' hour; one Avalon month is around one 'real-life' day; and one Avalon year amounts to the equivalent of two 'real-life' weeks. See HELP CALENDAR for details of Avalon's annual calendar.
The TIME command gives you both Avalon and 'real-life' time, as does the DATE command. Avalon's main clock follows London time (which is Greenwich Mean Time GMT or British Summer Time BST). If your timezone is not listed here, bring it to the attention of the Gods.
