hour

 

 

Description

The hourfunction returns the hour of a Date or Time argument. The value of the hour is calculated on the basis of a 24 hour clock and ranges from 0 (12:00 AM) to 23 (11:00 PM).

When to use

The hour function is used to extract the hour component from a Date/Time object.

 

Syntax

(hour date-value )

(hour time-text )

(hour Julian-date )



Name Description AIS Types
date-valueAn Analytic Information Server Date valueDate
time-textA time string in the form "hh:mm:ss AM/PM" where hh is the number of hours (0-24), mm in the number of minutes (0-60), ss is the optional number of seconds (0-60) and AM/PM optionally specifies morning or afternoon. If you use 12 hour time, you must include AM or PM; if you use 24 hour time, do not include AM or PM.String Text
Julian-dateA Julian date with a fraction extension representing the time for that date. The first two digits after the decimal point in the serial number correspond to a fraction of a 24 hour day. For example 0.00 corresponds to 12:00 AM; 0.25 corresponds to 6:00 AM; 0.50 corresponds to 12:00 Noon and so on.Date


Returns:

An Integer that represents the hour component of the argument

 

Examples

Here are a number of links to Lambda coding examples which contain this instruction in various use cases.

Example_Date_hour_001

These examples return the hour component of the date argument using the different date formats.
