Impact
Roughly 40-50 occurrences per day for last several weeks with occasional spikes.
Seems to be happening on both mobile and desktop versions of the site (more frequently on Mobile though).
Notes
"Unsupported time zone UTC" errors are getting thrown in the creationDate computed property of the Quickview component. This is probably an issue of inconsistent data from the underlying files themselves; if some files have specified a date format we can't currently handle, we'll need to rework the way "creationDate" is calculated or just not show it for problematic files.
