@vhscampos , do I understand correctly that this change means `EOVERFLOW` can now be expected to be defined in _all_ builds of LLVM libc?

If so, then we can also remove the previous [compensation code](https://github.com/llvm/llvm-project/blob/23c5322b0bc38a6bcd22f26d06e230b2845e68a0/libc/src/time/time_utils.h#L39-L48) in the time functions.
