Open Stack

Simo, we were planning to normalize times into UTC prior to putting into datastore, but didn't know if it would be too stringent to make clients also conform to UTC to use the API. Using UTC on both sides of the API does seem safer and more robust overall though, so we could enforce this in our code base for sure. 

Would anyone out there object to a UTC-only mode of operation for barbican?

Thanks,
John

You should always use UTC dates in barbican, using/allowing timezones is
only going to hit you back, badly.

Simo.
