I just added BSDCan as June 11-14 2025, but when I load https://developers.events/#/2025/list I see:
10-Jun 13-Jun BSDCan 2025 [www.bsdcan.org](https://www.bsdcan.org/2025/) Ottawa, ON (Canada)

It looks like https://developers.events/all-events.json has starting and ending timestamps at 00:00 UTC on the 11th and 14th respectively; I don't think the exact time of day is used or displayed anywhere on this site, but since I'm in Canada I'm wondering if those timestamps are getting converted to my local timezone and thus ending up with the wrong dates.
