What is the difference between Auto Generate and Auto Increment Build Number?

Question

I am using Delphi XE3. In project’s version information, I see there is a “Auto Increment Build Number” and a “Auto Generate Build Number” option. What is the difference between these two, I have read the manual but cannot find any difference. I think both of them will just increase the build number by 1 each time I invoke the build command for the project, is that correct?

No, they both apply only for application build (not compilation), but they are semantically different.

Auto generate build number option produces x.x.d.s version number, where d is the number of days since 1/1/2000 and s number of seconds since midnight divided by 2 (applies to Delphi XE3 for Win32 & Mac OS X target platforms and may differ for different Delphi versions and platforms).

Auto increment build number option only increments build number b in x.x.x.b version number by value 1.
