Impossible (past) predictions for certain routes


#1

Many users have been complaining that the bus route feature on the legacy API is returning impossible results. eg: Bus to reach the upcoming 5 bus stops within 1 minute in total, and some predictions returning a time in the past.

For example yesterday at: 1526991567098 unixtime = 2018-05-22 T12:19:27+00:00 when the request was made.

Which is showing a prediction time of 2018-05-22T12:15:43+00:00, which is roughly 4 minutes in the past.
