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.

Recently changed in this version

Added SNTP support. All the displayed times are now computed from a networked precision timebase.

Switching between the digital and analog clocks has become easier, because it is now a menu item instead of a preference setting.

    I have my Tablet set to Rotation Locked, but this app overrides that. It's most inconvenient and I request that it be fixed, please! Then I will give this very helpful app Five Stars!

    Wonderful App ! Would be much better if a calculator was included to tell at what local time would a particular sidereal time frame would occur.

    Great app. Would be even better with a sidereal alarm setting.

    Should be illuminated with red light to preserve night vision. Otherwise great for use at the telescope.
