Description

This function sets the start time to be used for the CALDB query. The start time should be in "HH:MM:SS" format, and can also be set by the calSetSate() function.

This field matches the time parameter of the quizcaldb tool - although you can not set it to "now" - and can be set equal to the contents of the FITS TIME-OBS keyword, or the time part of the DATE-OBS keyword.

The caldb module is not available by default; to use it in a S-Lang program, it must be loaded using the S-Lang require() function:

  require("caldb");
