Sjw/timestamp validation

[supernullset]

Adds validation to _t values, ensuring that the values are valid unix timestamps.

Could you factor this validation logic into a separate method? Raising the exception only to be caught locally seems a bit ungainly, though I understand it's necessary given #log_error.

Otherwise, note your regular expression pattern is unanchored and arguably a bit overspecified; I'd suggest /\A\d+\z/ instead. It's also necessary to return after handling the exception, as otherwise the tracking request is still issued. Finally as a very minor style nit, our guide advises against and in favor of &&.

I could! I thought that since its only going to be used right here, bringing it out would be overkill.

Totally agree about the raise here, I am not happy about it but I am working with the patterns in here.

Good calls on the rest, thanks for spotting it!

@njm do we want to return here as well? I think we would.

Couldn't hurt as a defensive play, though at the same time I'd be comfortable leaving that piece untouched.
