This looks like an odd way to do this conversion to a time_t value.

You're aware the Date object has multiple constructors? https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/Date

So, I think you could boil function this down to a single line that doesn't involve any string formatting or parsing:
`return new Date(pYear, pMonthNum - 1, pDayNum, pHour, pMinute, pSecond === undefined ? 0 : pSecond);`

What is a "TimeTF"?

Or instead of this function just do:

```js
var t = Date.parse(format('%s-%s-%sT%s:%s', yearStr, monthNumStr, dayNumStr, hourStr, minuteStr)) / 1000;
if (isNaN(t)) spontaneouslyCombustRatherThanSetIncorrectScanPointerTime();
```

TimeTFFrom.. was a typo.
Sometimes it would be good to find better documentation on things, such as the Date class constructor in this case..
