If parsing the time zone from the calendar feed fails, loc would be nil and therefore the subsequent call checkEvents() would fail with a panic, because the availability check requires the time.Location to be not nil.

If parsing the time zone from the calendar feed fails, `loc` would be
`nil` and therefore the subsequent call `checkEvents()` would fail with
a panic, because the availability check requires the time.Location to be
not `nil`.
