InstallMate sets this variable to the day number of the current build, with 1 January 2000 being day number 1. See Build-time variables for details about when InstallMate assigns values to build-time variables. The day number is set according to the local timezone.
Note: This variable is primarily intended for use in build actions. Therefore, and because it might contain potentially sensitive information about your development system, it is not saved in the installer's database by default. If you want to use this variable as part of your installer, you must check its Include in installer box in the Symbolic Variable attributes pane. If you fail to do so, InstallMate will issue a BLD:W0103 diagnostic when you build the project.
You can refer to it as <BuildDayNo>. In conditional expressions you can omit the brackets and use tests like BuildDayNo >= 2900. Do not set this variable directly; it is set automatically each time InstallMate builds a project.
