Review comment:
this prints UTC as "0:00" (which is OK, but "+00:00" is more standard)
and UTC-0:30 as "0:30" (which is wrong -- this time zone doesn't really exist,
but still)
```suggestion
tzofset << (tzbias >= 0 ? '+' : '-') << std::setfill('0') << std::setw(2)
<< std::abs(tzbias) / 60
<< ":" << std::setfill('0') << std::setw(2) << std::abs(tzbias) % 60;
```
