[cfe-dev] when did -Wdate-time appear in Apple's clang builds?

[René J.V. Bertin via cfe-dev]

Hi,

Can anyone please tell me the version number of Apple's clang that introduced support for the -Wdate-time argument, or else where I can find this information?
I understand it's supposed to be supported in clang 3.5, but not yet in "Apple LLVM version 6.0 (clang-600.0.57) (based on LLVM 3.5svn)".

Thanks,
R.
