palDtt
palDtt
- Return offset between UTC and TT
- Description:
- Increment to be applied to Coordinated Universal Time UTC to give
International Atomic Time (TAI).
- Invocation:
- dat = palDat( double utc );
- Arguments:
-
-
utc = double (Given)
-
UTC date as a modified JD (JD-2400000.5)
- Returned Value:
-
-
dat = double
-
TAI-UTC in seconds
- Notes:
- This routine converts the MJD argument to calendar date before calling
the SOFA iauDat function.
- This routine matches the slaDat interface which differs from the iauDat
interface. Consider coding directly to the SOFA interface.
- See iauDat for a description of error conditions when calling this function
with a time outside of the UTC range.
- The status argument from iauDat is ignored. This is reasonable since the
error codes are mainly related to incorrect calendar dates when calculating
the JD internally.
