Which time zones follow Daylight Saving Time?

The lists below show which time zones observe Daylight Saving Time (DST), and which ones do not.  The names of the time zones that observe DST change when Daylight Saving time begins each year. For example, Morocco Standard Time becomes Morocco Daylight Time. However, the names always show as 'Standard' in Replicon.

Replicon accounts for the change to and from DST automatically. If a user makes an ambiguous time entry (i.e. adds an in or out time that occurs during the hour that is repeated when clocks are set back), users will be prompted to choose whether they meant their entry to appear in the first or second occurrence of that hour.
