Modifying the system date Hide the details

DateSys(<New date>)
<New date>: Character string, Date or DateTime variable
New system date. This date can correspond to:
  • a character string in YYYYMMDD format (YYYY corresponds to the year, MM to the month and DD to the day).
  • Versions 24 and later
    a character string in YYYYMMDDHHmmSSCC format (YYYY corresponds to the year, MM to the month, DD to the day, HH to hours, mm to minutes, SS to seconds and CC to hundredths of a second (use CCC for thousandths of a second)). In this case, only the date is taken into account.
    New in version 24
    a character string in YYYYMMDDHHmmSSCC format (YYYY corresponds to the year, MM to the month, DD to the day, HH to hours, mm to minutes, SS to seconds and CC to hundredths of a second (use CCC for thousandths of a second)). In this case, only the date is taken into account.

  • a Date variable.
  • Versions 24 and later
    a DateTime variable. In this case, only the date is taken into account.
    New in version 24
    a DateTime variable. In this case, only the date is taken into account.
    a DateTime variable. In this case, only the date is taken into account.
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.

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.
