Totally missed this thread and ended up implementing -Wdate-time earlier 
today as a means to validate our new system header warning suppression 
semantics.

Please see r210511 + r210512 for the approach taken. Apologies to 
Prathamesh whose original patch appears to have been on the right track 
(modulo IdentifierInfo comparisons and missing __TIMESTAMP__ case).
