Could you say more about how to reproduce this error? For example, what command did you run to cause this error message?

The default Rust Windows targets do not support Windows 7. In this case, any use of SystemTime::now (i.e. via Chrono) would cause GetSystemTimePreciseAsFileTime to be imported and thus fail on Windows 7.

There are Windows 7 rust targets but nobody has stepped forward to maintain them as tier 2 and, as Windows 7 has been out of support from the vendor for many years now, there's not any help from there either. This is important because unless/until it's tier 2, it can only be used by compiling rustc from source.
