This was actually _your_ question,  6d8c4212bd2dbb884a9b7c9467f4dadc8da8cd0b:
```
RemoveDates(): move datetime string literal computation to compile-time
- comment on uncertainty of two-digit hh:mm:ss and time-zones shorter
  than three letters.
Pointed out by Edward Welbourne
```
+1 for providing an answer to your own q :-)
