Syntax

Finding out the system time and initializing a WLanguage element with the system time Hide the details

<Element> = Now()

<Element>: Character string or type corresponding to the element

The result of the function changes depending on how the function is used. Element to initialize. This element can correspond to:
a character string. It will contain the system time in HHMMSSCC format (HH corresponds to hours, MM to minutes, SS to seconds and CC to hundredths of a second).
a Date, Time or DateTime variable.
a Date, Time or DateTime item.
an edit control or a Date, Time or DateTime column.
an attribute of a Looper control associated with the Value property of an Edit control or a Date, Time or DateTime column.
In this case:
the Date elements will be initialized with the system date.
the Time elements will be initialized with the system time.
the DateTime elements will be initialized with the system date and time.
Now returns the time only.

Modifying the system time Hide the details

Now(<New time>)

<New time>: Character string or Time variable

New system time in HHMMSSCC format (HH corresponds to hours, MM to minutes, SS to seconds and CC to hundredths of a second).

Remarks

Caution: To modify the system time, you must have the administrator rights on the current computer.
To get the time in a format other than HHMMSSCC, the string must be formatted using DateToString, Right, Left, etc.
The HHMMSSCC format was chosen because it allows you to compare two times with hundredths-of-a-second accuracy.
The system time corresponds to the current time defined on the server.
In this version, Now can only be used to return the system time of the current computer (or the one defined for the browser computer).
