hour(theDate[,value])

Alternatively, use Date.hour.

hour(theDate)

returns the hour element from the theDate date/time expression, which may simply be a date-type attribute value.

hour(theDate,value)

creates a new date based on the theDate expression, but in which the hour is value. theDate is not changed - unless theDate is an attribute and the attribute is re-setting itself:

$MyDateA = hour($MyDate,14) $MyDate is unaltered

$MyDate = hour($MyDate,14) $MyDate is changed

Examples. If $MyDate is July 4,2009 09:30, then

$MyDate=hour($MyDate,19) 

will change $MyDate to July 4, 2009 19:30.
