BUG: DatetimeIndex.snap incorrectly setting freq
Sounds good though I think we want to deprecate this function? #27098 > though I think we want to deprecate this function

Yah, i think the argument was that `round` can do what it snap does, but there was a comment somewhere that this isnt quite accurate.  Regardless, fixing the bug is worthwhile. Should infer the frequency in case the result is actually regular? (to keep the correct behavior for those cases) > Should infer the frequency in case the result is actually regular?

Either way I guess.  I tend to prefer not inferring in most places. thanks
