Tdb julian date
JD and BJD are defined independent of the time standard. JD can be expressed as e.g. UTC, TT, TAI, TDB, etc. The differences between these time standards are of the order of a minute, so for better than one-minute accuracy, the time standard must be stated. While many quote the BJD in UTC, UTC is discontinuous and drifts with the addition of each leap second, and should therefore only be used for relative timing over a short time span (~1 year). For high-precision, absolute ti… WebTDB = TT + 0.001658 sin( g ) + 0.000014 sin( 2g ) seconds where g = 357.53 + 0.9856003 ( JD - 2451545.0 ) degrees and JD is the Julian Date. smaller than 20 microseconds, is given in the Explanatory Supplement to the Astronomical Almanac [ref 4]. Planetary motions are now computed using TDB.

Labels ------ If you add more information to the string, STR2ET can make a more informed interpretation of the time string. For example: 1988 June 13, 3:29:48 P.M. is still regarded as a UTC epoch.
WebJD (Julian Date): Number of days since Greenwich mean noon on January 1, 4713 B.C. Note that JD may be used in conjunction with all of the above time systems; whenever the required accuracy dictates this, the time system used should be indicated: e.g., JD (TT). MJD (Modified Julian Date): Equals JD - 2400000.5.
