Timestamp


Timestamp -> Function result

Parameter	Type	Description
Function result	String	Current time returned using ISO format with milliseconds

Description

Timestamp returns the current UTC time in ISO format with milliseconds, i.e. yyyy-MM-ddTHH:mm:ss.SSSZ. Note that the "Z" character indicates the GMT time zone.

Each time returned by Timestamp is expressed according to the ISO 8601 standard. For more information about this standard, refer to: https://en.wikipedia.org/wiki/ISO_8601

Note: This function is not suitable for timing purposes; you should use Milliseconds when you want to measure elapsed time.

Example

You can use Timestamp in a log file to know precisely when the events occurred. As shown below, you may have several operations occurring during the same second:

 $vhDocRef:=Append document("TimestampProject.log")

 $logWithTimestamp:=Timestamp+Char(Tab)+"Log with timestamp"+Char(Carriage return)

 SEND PACKET($vhDocRef;String($logWithTimestamp))

Result:
