caladdhours() Function

This function adds a given number of hours to a Date and Time plus any non-working hours (as designated on the process calendar) and returns the resulting Date and Time.

Syntax

caladdhours( start datetime, number, [calendar name] )

start_datetime: (Date and Time) The starting Date and Time.

number: (Integer) The number of net work hours to be added to the starting Date and Time.

calendar_name: (Text) This optional parameter accepts the name of a system calendar; otherwise, the default calendar is used.

Returns

Date and Time

Notes

The function only returns Date and Time values that fall within the working time defined in the process calendar.

It correctly calculates results across daylight saving time boundaries.

If the start_datetime value is a non-working time, adding 0 hours returns the same Date and Time given as the start_datetime; adding 1 or more hours returns the next working time plus that many work hours.

Passing a calendar name allows you to calculate working hours using an alternate system calendar, if you have multiple calendars configured.
