Time Formats

From JMARS Wiki

JMARS has many fields where users can either input or display a time. The following are the acceptable time formats:

1. Ephemeris Time (et)

et:#########                       (ex: et:239719865)

2. Spacecraft Clock (sclk)

sclk:##########                   (ex: sclk:0870915330)

sclk:#/##########                 (ex: sclk:2/0870915330)

3. Orbit

orbit:#####                           (ex: orbit:25040)

orbit:#####+hh:mm:ss           (ex: orbit:25040+1:35:00)

4. Coordinated Universal Time (UTC)

utc:yyyy-dddThh:mm:ss         (ex: utc:2007-218T19:45:00)

utc:yyyy-ddd//hh:mm:ss         (ex: utc:2007-218//19:45:00)

yyyy/mm/dd-hh:mm:ss           (ex: utc:2007/08/06-19:45:00)

yyyy MMM dd hh:mm:ss         (ex: utc:2007 aug 06 19:45:00)

• Note: "#" represents a single digit (0-9)

Local users can run the showtime_themis script to translate a time in one of the acceptable formats into all of the other acceptable formats. For example, entering "orbit: 25000" will give the following result:

> showtime_themis orbit:25000 

UTC:  2007-215 // 17:47:30.172
UTC:  2007 AUG 03 17:47:30.172
ET:   239435314.354880
SCLK:  2/0870630778.171
ORBIT:  25000+0:00:00.000000
