Configuration Control9.2.4. Compile Date and TimeCompile date and time is saved in generated prom files and can be accessed from arunning system via diagnostic tools. In some cases, it may be necessary to verify that allthe application data in a particular prom file is the same as that specified by a given setof CAA input files. Since compile date and time are part of the prom file contents,recompiling the same input data generally does not produce identical prom filesbecause the date and time are different for each compile.A feature is available (VPI CAA 029B / 023I and later, CTC2-s CAA 014E and later) formanually entering date and time values to match those of a previous compile. Themanually entered data is substituted for the PC system clock date and time that arenormally used. Assuming all other application data and system software versions areidentical, recompiling with the manually entered date and time then produce identicalprom contents. Manually entered date and time values are listed in CAA report files aswell.CAUTIONManual date and time should be used with caution under specialcircumstances only, compile date and time may be an important aspect ofconfiguration control.To manually enter compile date and time values, right click on the application folder inthe CAAPE's File View and click Set Manual Date/Time. A dialog box is displayed forentering compile date and time values to be stored in prom. These values are good foronly one compile, then they have to be entered again or the next compile makes use ofPC system clock data as usual. This is done to prevent accidentally doing multiplecompiles with the same manual date and time set.To clear previously-entered manual date and time values before doing a compile, rightclick on the application folder in the CAAPE's File View and click Cancel ManualDate/Time.P2512A, Rev.
