The Sidereal Time App gives the user a simple and quick way to determine:

- Local Apparent Sidereal Time (LAST) based on longitude
- Rough estimate of LAST based on Time Zone
- Greenwich Apparent Sidereal Time (GAST)
- Select one of 30 Stratum-1 NTP servers or add your own to synchronize the clock against the primary network time standard

The App uses core location (GPS, cellular triangulation and/or Skyhook Wireless's Wi-Fi system) to determine the users present position and hence his LAST. The user may also manually select the longitude coordinate to determine LAST or make a rough estimate by selecting a Time Zone.

A running clock with the Coordinated Universal Time is presented in parallel with the Sidereal Time clock.

Local Apparent Sidereal Time at any location differs from the Greenwich Sidereal Time value of the same moment, by an amount that depends on the longitude of the location. When one moves eastward 15° in longitude, sidereal time is larger by one hour and hence wraps around at 24 hours. Unlike computing local solar time, differences in longitude and time are counted here to the accuracy of measurement, not just in whole hours.

2011-03-07

Built for iOS 4.3

1.5

Landscape orientation now supported.
Following bug has been corrected:
• Incorrect Timezone during daylight savings time

1.4

2010-07-13

Rebuilt for iOS 4.
Following bugs has been corrected:
• Stability problem related to "Zone" and "GMST" modes

1.3

2010-04-07

Following bugs related to longitudes west of Greenwich (negative values) has been corrected:
- Longitude received through iPhone location services not shown correctly in Longitude Button
- Longitude in Picker in some cases not transferred correctly to Longitude Button, hence showing an offset of 1" from selected value

1.2

2010-04-01

Following bugs has been corrected:
- UTC time incorrect during daylight saving time.
- Initial startup state after installation incorrect: "Local Apparent Sidereal Time" with Longitude Button disabled.
- Longitude in Picker in some cases not transferred correctly to Longitude Button.

1.1

2010-03-18

Network Time Protocol (NTP) Service added:
- Select one of 30 Stratum-1 NTP servers (the primary network time standard).
- Add your own NTP server.
- When NTP service activated by user, the sidereal time and UTC clocks are updated every 15 seconds to an accuracy of +/- 0.1 sec.
- Status text is shown at the bottom of main view when the NTP Service is active.

Minor redesign of GUI:
- Reordered Sidereal Time functions in segmented button control.
- Naming of segmented button control functions changed to more appropriate abbreviations: "GM" (Greenwich Mean) changed to "GMST" (Greenwich Mean Sidereal Time) and "Position" changed to "LAST" (Local Apparent Sidereal Time).
