Duration (Type of variable) In french: Durée
The Duration type is used to easily handle the intervals of dates and times. The DateTime type can be used to perform calculations (subtraction, addition, ...). See Operations that can be performed on the Duration type for more details. Remarks: - Several properties can be used with the Duration type, to retrieve the number of days or minutes for example.
- To assign a duration coming from the result of a function, use StringToDuration.
- See Declaring a variable for more details on the declaration of this type of variable and the use of WLanguage properties.

Syntax
Declaring and initializing a variable Hide the details
<Variable name> is Duration = <Value>
OR
<Variable Name> is Duration
<Variable name> = <Value>
<Variable name>: Name of variable to declare. When several variables of the same type are declared and initialized on the same line, only the last variable is initialized. <Value>: In most cases, a duration is the result of an operation performed on Date, Time or DateTime variables.
This value can correspond to: - a string of characters,
- an integer (number of milliseconds of duration),
- a duration (for example, another Variable of the duration type),
Versions 23 and laterthe direct indication of the duration (: 30 s). New in version 23the direct indication of the duration (: 30 s). the direct indication of the duration (: 30 s).
0 is used to re-initialize the duration. Remarks If a Variable of type Duration is handled: - thanks to a string, this string is in the format: "+DHHMMSSLLL" (days, hours, minutes, seconds, thousandths of a second).
- through an integer, this integer corresponds to the number of milliseconds of time.
- thanks to a Duration, this Duration can correspond to a Variable of type Duration or to the direct indication of the Duration.
In most cases, a duration is the result of an operation performed on Date, Time or DateTime variables. This value can be a duration. 0 is used to re-initialize the duration. The properties that can be used on the durations The following properties can be used on the durations: | | | InHours | Returns or modifies the number of hours corresponding to a duration. The number of hours is expressed in real format. | | InDays | Returns or modifies the number of days corresponding to a duration. The number of days is expressed in real format. | | InMilliseconds | Returns or modifies the number of milliseconds corresponding to a duration. The number of milliseconds is expressed in integer format. | | InMinutes | Returns or modifies the number of minutes corresponding to a duration. The number of minutes is expressed in real format. | | InSeconds | Returns or modifies the number of seconds corresponding to a duration. The number of seconds is expressed in real format. | | Time | Returns or modifies the number of hours. The number of hours is expressed in integer format. | | Day | Returns or modifies the number of days. The number of days is expressed in integer format. | | Millisecond | Returns or modifies the number of milliseconds. The number of milliseconds is expressed in integer format. | | Minute | Returns or modifies the number of minutes. The number of minutes is expressed in integer format. | | Second | Returns or modifies the number of seconds. The number of seconds is expressed in integer format. |
See Operations that can be performed on the Duration type for more details.
StartTime is Time = "1330"
EndTime is Time = "1730"
ConferenceDuration is Duration = EndTime - StartTime
Info("The conference lasted: " + ConferenceDuration..Hour + " hours")
Important: To store the values of the properties listed in the above table, you must respect the type of variable returned by each property. For example:
MyDuration is Duration
HowManyHours is real
MyDuration..Day = 5
HowManyHours = MyDuration..InHours
Info(MyDuration..Day + " days = " + HowManyHours + " hours.")
In this example, the HowManyHours variable must be declared as real (and not as integer). If this variable is declared as integer, its value will be approximative. The Duration type is used to manage the durations included between plus and minus 2 billion days. The precision is up to the millisecond. Displaying a duration in an edit control
