The  SPECTIME  external  package  provides  a  spectral  exposure   time
calculation  engine, SPTIME, that is driven by database files describing
the various components of a spectroscopic system.  SPTIME  can  be  used
directly  or  with different user interfaces for specific spectrographs.
These include IRAF scripts and a web interface.
