Investigate submission bug

[kjduensing]

Purpose

Fixing this bug will allow us to communicate that everything is ready in staging. Also it'll make things... work.

Context

When submitting a claim for an appointment, vets-api returns a 400 error. Investigating the logs shows an error message of "Invalid appointment time provided (appointment time cannot be nil)." This appears to happen before the call to the Travel Pay API is made.

We have investigated and fixed:

• the non-local time being sent from the frontend
• the backend using the non-local time (PR out)

Questions/thoughs:

• What we've investigated so far shouldn't give the error message "appointment time is nil". Why is the appt time nil?

Acceptance Criteria

• Bug identified
• Submission successful
