Couple of points
- this should be a target based requirement. This will still fail if you ran
lit on z/OS with the default triple being arm.
- the problem is that arm is still using a 32-bit time_t. I'd mark this as
unsupported on arm target(s) rather than only supported on z/os. Most
platforms have moved to 64-bit time_t and this is relevant on those platforms.
Check out clang/test/Preprocessor/SOURCE_DATE_EPOCH.c.
Try this.
```suggestion
// REQUIRES: clang-target-64-bits
