Select a Time Zone

Suntimes can be configured to use a given time zone (or other time standards).

System Time Zone

Suntimes displays time using the system time zone by default.

User-Defined Time Zone

Suntimes can display time using a specific time zone.

Choose user-defined, tap to sort the list, then select a time zone from the drop-down.

Tap -> Recommend Time Zone to suggest a time zone closely matching local mean time.

Note

Time zone recommendations work best for named places in the IANA time zone database and may produce inaccurate results for other places.

Tip

Choose a time zone within a couple hours of local mean time for best results.

Verify the time zone if reported times seem inaccurate or don’t make sense. A mismatch between the time zone and location is a common misconfiguration.

Tip

Suntimes will display an info icon when daylight saving (or a similar rule) is in effect.

Time Standard

Suntimes can also display time using:

Local Mean Time (LMT)
Apparent Solar Time (LTST)
Local Sidereal Time (LMST)
Greenwich Sidereal Time (GMST)
Coordinated Universal Time (UTC)
