The problem appears to be reusing a connection with a timezone set for
that session from a previous test that was ran. The report timezone is
not specified, but the timezone is set on the session from a previous
run. This results in the timestamps being return as UTC, but shifted
back 7 hours (as if it were pacific time).

This commit just specified a report-timezone of UTC to avoid that issue.

Change "xray" to "x-ray" throughout

Date dimension options should apply to unix timestamps

They have a base_type of numeric but a special type of DateTime. This
adds the check for special type when associating dimension options to
a field.

This commit wraps the timezone detections stuff in some try/catches so
that if there's an issue parsing one of the timestamps from the
database, it doesn't cause the whole sync process to fail.

If a failure happens, it's logged as a warning, the timezone field in
the database is not updated and the sync process proceeds.
