12月22日的World Times应用程序分析

This app displays the time in over 400 world-wide locations as well as their Greenwich Mean Time offset. Locations are indexed and ordered alphabetically within their respective geopolitical regions. An additional page facilitates the calculation of the time difference between 2 time zones calculated from the "GMT" offsets which can be obtained from the table view page. For locations that do not display the "GMT" offset it can easily be calculated by subtracting the the "GMT" time from the local time. The app displays the day of a location relative to the day of the current time zone device setting (i.e. "Today", "Tomorrow" or "Yesterday") in 32 languages.
