We always merge edk2 portions before edk2-platforms, so once it's merged the only ordering requirement is that your edk2 isn't older than your edk2-platforms.

In this particular case, it wasn't actually important, we just ended up with mismatched expectations. Since it was fairly isolated code that I had already been able to test build in my environments when it formed part of the original driver.

[edk2-devel] [PATCH 1/1] EmbeddedPkg/TimeBaseLib: Add macros to get build year/month/day
These can be used, for instance, to automate the population of an SMBIOS Type 0 BIOS Release Date when building a UEFI firmware (which is how we plan to use these macros for the Raspberry Pi platform). These macros should work for any compiler that follows ISO/IEC 9899, but we add a check for the compiler we have tested to be on the safe side. Note that we decided against adding a #error or #warn for compilers that haven't been validated, as we don't want to introduce breakage for people who may already be using the header with something else than gcc, MSVC or Clang. Instead, we expect those to send a patch that adds their compiler to the list, once they have tested the macros there.
