AHELP for CIAO 3.4 calSetTime Context: caldb

Synopsis

Sets the time for the next CALDB query.

Syntax

calSetTime( Caldb_Type cal, String_Type start_time )

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.

Example

chips> cal = calCreateInfo
chips> calSetTime( cal, "04:12:45" )

Bugs

See the bugs page for the caldb library on the CIAO website for an up-to-date listing of known bugs.
