YYYY:MM:DD:HH:MM:SS.sss Time | Unitless | Text | Coordinated Universal Time. Displayed in the indicated format (2007:05:08:12:00:00.000). |
Julian Date | Unitless | Text | Coordinated Universal Time. Displayed in the Julian Date format. The Julian Date is given as the number of days from GMT Noon on 1 January, 4713 B.C. |
Jul Date Offset | Unitless | Text | Number of days elapsed past a user defined epoch. |
Modified Julian Date | Unitless | Text | Coordinated Universal Time. Julian date, shifted by 2400000.5 days (i.e. MJD = JD - 2400000.5). |
Julian Ephemeris Date | Unitless | Text | Terrestrial Dynamic Time (TDT), now replaced by Terrestrial Time (TT). Displayed in Julian Date format. TDT is equal to Atomic Time (TAI) plus 32.184 seconds. |
Gregorian GPS Time | Unitless | Text | GPS time. Displayed in Gregorian format. In STK, GPS time is defined as UTC plus the number of leap seconds since 1 Jan 1980. |
GPS Time | Unitless | Text | GPS time. Displayed as the weeks:seconds from 1 Jan 1980 00:00:00.00 (i.e. 1329:475213.000). In STK, GPS time is defined as UTC plus the number of leap seconds since 1 Jan 1980. |
GPS Z Count | Unitless | Text | Time elapsed since the GPS reference epoch (1 Jan 1980 00:00:00.00 UTC), measured in 1.5 second incremements. |
Mission Elapsed | Unitless | Text | Time elapsed past the scenario epoch. The format is number of days / time (121/18:30:00.000). |
