:robhudson, can you paste a traceback?

This is intermittent -- not happening for everyone all the time. If it is preventing people from doing work, let's promote to major and put in dev inbox.

For what it's worth, it worked for me just now, but Rob Hudson just had it ISE right before I tried it. Weird.

[Rob Hudson [:robhudson]]

I saw an error come in for this via Sentry:

https://errormill.mozilla.org/mdn/mdn/group/409935/

ERROR: AmbiguousTimeError: 2015-11-01 01:33:08

Is this problem still occurring?

Comment 5

[John Whitlock [:jwhitlock]]

Yes. We've switch Sentry instances, now tracked at:

https://sentry.prod.mozaws.net/operations/mdn-prod/issues/222629/

It is blocked by adding timezone-aware date times to Kuma, which is tracked in confidential bug 1142203.  A severely out-of-date PR is at mozilla/kuma#3334.

[John Whitlock [:jwhitlock]]

I've implemented an alternate fix in bug 1173189, where I just handle AmbiguousTimeErrors from the transition from daylight saving time to standard time (early November in the US). Timezone-aware datetimes will have to wait a bit longer.
