The %T format specifier for strftime is somehow still not implemented in mingw-w64, causing simplecpp to expand __TIME__ to an empty string. This is an issue with the compiler suite, but the easiest fix is to use the equivalent %H:%M:%S instead. C99's %T is defined to be equivalent to %H:%M:%S, so this change should be compatible with all implementations supporting strftime.

please create an issue.
if a test can be added that would be great.
I guess you could install mingw-w64 with this: https://github.com/marketplace/actions/install-mingw

We need a test that actually triggers the issue first. I will add MinGW workflow to the CI.

I started working on the MinGW CI in #475 (sorry it took so long) but that also exposed a number of different issues which should be looked at first.

Actually #475 confirmed that this fails and requires this change to succeed. So merging it.
