Hello,
C-u M-x sunrise-sunset (and today's date) says:
--8<---------------cut here---------------start------------->8---
Sat, Jan 19, 2019: Sunrise 7:54am (CET), sunset 4:13pm (CET) at Poznań,
Poland (8:19 hrs daylight)
--8<---------------cut here---------------end--------------->8---
Here are my settings:
--8<---------------cut here---------------start------------->8---
(setq calendar-latitude 52.4)
(setq calendar-longitude 16.917)
(setq calendar-location-name "Poznań, Poland")
--8<---------------cut here---------------end--------------->8---
(BTW, if anyone is ever near here, please drop me a line - we might be
able to meet in person;-)).
And C-u M-: calendar-time-zone says (correctly) 60.
However, https://www.timeanddate.com/astronomy/poland/poznan (for today)
says:
--8<---------------cut here---------------start------------->8---
Sunrise Today: 07:51↑ 124° Southeast
Sunset Today: 16:14↑ 237° Southwest
--8<---------------cut here---------------end--------------->8---
I also noticed that other online services give yet other results.
Anybody knows why the difference(s)?
TIA,
