Time Difference

Time differences between different time zones are simple to work out as a result of Universal Time Coordinated (UTC). As standard times are shown as positive or negative offsets of UTC, time differences are calculated by establishing UTC, and calculating the times in each zone from there. Differences to standard times as a result of Daylight Savings Time also need to be taken into account, if applicable.
