If you are using the V16Pro and WinScriptLive, use the "triggers" dialog to create a Real-Time clock trigger.
If you are using WinScript 3.0 and a V16+, V4+, V2+ or Interactivator, the ESE protocol that you can assign to any given port sets the following variables with the current date and time of day:
var31 - seconds
var30 - minutes
var29 - hours
var28 - year
var27 - day
var26 - month.
Use these variables (rename them if you like) as your date variables.
