SUBROUTINE sla_DTF2R (IHOUR, IMIN, SEC, RAD, J)
*+
* - - - - - -
* D T F 2 R
* - - - - - -
*
* Convert hours, minutes, seconds to radians (double precision)
*
* Given:
* IHOUR int hours
* IMIN int minutes
* SEC dp seconds
*
* Returned:
* RAD dp angle in radians
* J int status: 0 = OK
* 1 = IHOUR outside range 0-23
* 2 = IMIN outside range 0-59
* 3 = SEC outside range 0-59.999...
*
* Called:
* sla_DTF2D
*
* Notes:
*
* 1) The result is computed even if any of the range checks fail.
*
* 2) The sign must be dealt with outside this routine.
