UTC is universal coordinated time (it's french), or alternatively, Greenwich Mean Time. It never changes...that means when we hve daylight saving time, UTC doesn't change. So: For standard time, UTC is 5 hours ahead of Eastern, 6 ahead of central, 7 ahead of mountain, and 8 ahead of pacific. When daylight saving time kicks in, UTC is: 4 hours ahead of easter, 5 ahead of central, 6 ahead of mountain, and 7 ahead of pacific. If you live in parts of Indiana, or in all of Arizona or Hawaii, you don't observe this silly daylight saving time practice, so you'd be on standard time all year and should calculate UTC accordingly. -- Buddy Brannan, KB5ELV ------------------------------------------------------------ Help us bring our child home!
