Sidereal Clock

Sidereal Clock


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.

Recent changes:
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.

Very cool! I was looking for a replacement for Sidereal for PalmOS by Edgar Bonet and this has everything I wanted ( Local Mean Time, Local Apparent Time, Julian Day, Modified Julian Day ), plus more ( Equation of Time, etc. )

No font choice Font matters to view time at a glance without glasses. Often I only want to the minute or even nearest 5 or even 10 main AT A GLANCE.

Good app. Needs a way to default to the analog clock. Wouldn't mind having a night mode as well.

Menu Missing? Does the non-paid version even offer a menu to change between digital and analog mode? If it does it's hidden nicely. If you need to pay for analog mode then that should be clearly stated.

I'd give five stars if the screen didn't auto rotate! 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!
