Every heard of daylight savings time (DST)?

Can be adjust client-side, or wherever you need to present it, rather than adjusting stored data.

This is only sometimes true. Cases like opening hours and daily batch processing rely on local time. Persisting the values in UTC mean best case you are wrong half of the year and worst case all of it.

Just because you're storing the time in UTC doesnt mean you can't also store the timezone, and lots of other related data too.

6am in my time zone is two different times in UTC. Right now it is 14:00 UTC. But when DST starts it will be 13:00. So what UTC value do you insert into your database for the opening time of the coffee shop? And how do you convert?
