The Sidereal Clock displays sidereal times and several other time standards, such as UTC, solar time and julian date. It has 3 time displays and you can choose what time to show in each of them.
All the displayed times are computed from the Sidereal Clock's own timebase which is synchronized to an external high precision NTP time server.
To compute the local times it gets your longitude via GPS.
The Sidereal Clock is supported by ads.
