Merge #18162: util: Avoid potential uninitialized read in FormatISO8601DateTime(int64_t) by checking gmtime_s/gmtime_r return value
12a2f377185a413b740460db36812de22ee2e041 util: Avoid potential uninitialized read in FormatISO8601DateTime(int64_t nTime) by checking gmtime_s/gmtime_r return value (practicalswift)
Pull request description:
Avoid potential uninitialized read in `FormatISO8601DateTime(int64_t)` by checking `gmtime_s`/`gmtime_r` return value.
Before this patch `FormatISO8601DateTime(67768036191676800)` resulted in:

```
The same goes for other very large positive and negative arguments.
Fix by simply checking the `gmtime_s`/`gmtime_r` return value :)
