UTC and ISO 8601, or GTFO

Posted by jpluimers on 2022/11/08

Always schedule your meetings in UTC, and use ISO-8601 date and time notation. Because time zone conversions are hard, especially with so many daylight saving time conventions.

I want not just a “UTC or GTFO” shirt, but a “UTC and ISO-8601, or GTFO” shirt.

It means I do not agree with [] Colin Nederkoorn on Twitter: “Pro tip: Don’t schedule recurring meetings in UTC if you live in a place with daylight savings.… “ with multi-time zone teams: having it in UTC will balance out the DST changes over the teams.

Some more relevant Tweets that triggered me writing this post:

(Most via [] schedule meetings in utc – Twitter Search / Twitter)

Reminder in 4.5 months: [] Shaun McCance on Twitter: “This is your semi-annual reminder that most of the US starts DST on March 14, most of Europe starts DST on March 28, and Australia ends DST on April 4. So you should just go ahead and cancel all your meetings now.”

There are always XKCDs too:
