Display Time only as Positive Values

[mboneil10]

In development mode, I ran into the following issue:

Should probably say "early" or "on time" next to the clock symbol. Not sure if this is also happening in production.

They're two separate data points, right? The status of the bus and its EDT? Arguably we're just accurately reporting inconsistent data.

I'm not 100% sure, but I believe @akaplo found that the only two values ever reported were "Late" and "On Time". Indeed that is the case e.g. right now:

$ curl -s --header 'Accept: application/json' 'https://bustracker.pvta.com/InfoPoint/rest/Vehicles/GetAllVehicles' | jq '.[] | .DisplayStatus' | sort -u
"Late"
"On Time"

$ curl -s --header 'Accept: application/json' 'https://bustracker.pvta.com/InfoPoint/rest/Vehicles/GetAllVehicles' | jq '.[] | .Deviation' | sort -n

Ugh. At first I thought, "Oh, look! there's a field OpStatus that sometimes contains the string "EARLY", perhaps that's a good source of information." Nope. Take a look at this grab-bag of :cow:

[akaplo]

Right, a vehicle's DisplayStatus is either On Time or Late. Unfortunately, best approach for our users is probably to check for a negative Deviation, flip DisplayStatus to whichever it isn't equal to, and strip out the negative. Ugh!

I think with this one @werebus, @sherson and I decided that it would be best to ask Avail if we can display "Early" or strip out the negative without any bad side effects.
