Time zone converter.
I try to make a timezone converter then I travelling to know open hours in two different countries
Like In USA and Sweden.
What I try to do was to get a reference to GMT and from that add +/- houres were I go so if I am in Sweden that's 1 h plus Finland 2h plus so on.
I tried many ways but get times to be like 27hours :-(
Sweden. 09:00 - 17:30 +1h
USA 15:30 - 22:00 - 5h
Thanks in forehand
