I'm sure there's huge demand for remote time sync . many buildings have dozens of these that need setting during daylight saving time change.

Pretty awesome. The only thing I would change is to put a USB battery between the usb wall power and the D1 mini. That way for power outages of < a couple of days or so you're clock will be fine.

What's the best way to periodically get time and date if your customers are big businesses with hostile IT departments?

Most 'big businesses' I've delt with have a time server someplace internal. It may be a stand alone NTP server, a network device like a Cisco router or a Windows AD server. You might ask the network team/Windows admin team nice and see what they have.

A great solution I've used plenty of times is to query websites like google.com. I use it whenever my rtc on my Linux laptop gets reset (as long as it's still in my history. Otherwise I just set it manually).
I’m curious how long it takes for the hands to drift to the point where the time difference is perceivable. Luckily the 30 millisecond pulse time is configurable.

It'd be interesting to see the logs or data on how the physical movement falls out of sync. It probably even correlates with temperature and humidity.

Keeping time in terms of hash-sigs that are in 64 bit architecture instance.
Some years ago I made a ESP-based clock that used 60 LEDs in a circle that project RGB shadows via a cone at the center. I used the same WeMos D1 Mini board.
I remember seeing this on Hackaday. Very clever idea!

Cute, but the original clock used to run on AA battery that needs a replacement every two years or so, and now it needs a power supply. Or some big battery recharge/replacement every few hours maybe days.
