Show Minutes Until Arrival Corrected By Timezone

[patrickdemers6]

When in a different timezone than Central, the minutes until arrival are incorrect. These should either be passed from the backend or calculated on the frontend while respecting timezone differences.

Current Behavior

If the bus is arriving in 10 minutes, someone on the west coast will see 130 minutes due to being two hours behind.

Expected Behavior

If the bus is arriving in 10 minutes, someone on the west coast will see 10 minutes until arrival.
