Sometimes it is needed to get a label text in a language that is different from the current one. To do that the labelId2String method of the SysLabel class can be used.
Example:
SysLabel::labelId2String(literalstr('@SYS1'), 'en-us');
Gives: Time transactions
SysLabel::labelId2String(literalstr('@SYS1'), 'de');
Gives: Zeit Transaktionen
