Syntax

Getting the system date Hide the details

<Result> = DateSys()
<Result>: Character string or Date variable
System date in YYYYMMDD format (YYYY corresponds to the year, MM to the month and DD to the day).
Remarks
  • To get the system date in a format other than YYYYMMDD, the string must be formatted using the DateToString, Right, Left functions or the date properties. The YYYYMMDD format was chosen because it allows you to check the order of dates. This would not be possible with a date in YYYYDDMM or DDMMYYYY format, for example.
  • On all current systems, the year of the system date can be between 1920 and 2120.
  • Caution: To modify the system date, you must have the administrator rights on the current computer.
  • Universal Windows 10 AppAndroidAndroid Widget iPhone/iPadIOS WidgetApple WatchMac Catalyst In this version, DateSys can only be used to return the system date (of the current computer or the computer where the browser is running).

Comments
WinDev for a Windows application: beware of user privileges!
When trying to set the computer's clock to a certain date / time, the functions DateSys("20151231") or TimeSys("18:00:00") will not return an error code if the computer's clock is not set (mostly because of missing admin rights). If you wish to be able to act on a returned error then use the API SetSystemTime.
