Tests are failing but my response is correct

Tell us what’s happening:
I did the project for Timestamp Microservice. I believe all my responses are correct but the tests fail on the last two when the timestamp is empty.

The link is here: https://rain-actually-monitor.glitch.me
I am doing this from South Africa, but that should not make a difference. The left is my service called with /api/timestamp and the right is your example called with the same.
