def fromMJDDate(mjd: Int, timeScale: TimeScale, seconds: TimeFormat): AbsoluteTime

Creates an AbsoluteTime from a Modified Julian Date (MJD).

Creates an AbsoluteTime from a Modified Julian Date (MJD).

==Math Note==

  • MJD = JD - 2400000.5
  • Conversion:
 JD = MJD + 2400000.5
 seconds_since_J2000 = (JD - 2451545.0) * 86400

Value parameters

mjd

the Modified Julian Date

seconds

optional seconds offset (default = 0)

timeScale

the timescale to use

Attributes

Returns

an AbsoluteTime corresponding to the given MJD

def now(): AbsoluteTime

Returns the current system time as an AbsoluteTime in UTC.

Returns the current system time as an AbsoluteTime in UTC.

==Math Note==

  • Uses Instant.now (system clock, UTC).
  • Conversion: epoch_seconds → J2000 offset.
