I'm about to get a Tactix Delta watch and I know it has a dial for UTC time.
Can someone please explain in an easy way what UTC is used for? Does it have any use for a normal person in Scandinavia?
I tried to google it but didn't get any smarter...
Thanks 
Hi fenixuser that is a nice watch you are thinking of. UTC is based on 0 degrees longitude and is fixed throughout the year with no daylight saving. It has traditionally been used by navigators fixing…
Well, the only time I have use of UTC time is in astronomy. I would say that all astronomical events are (or should be) reported in UTC time.

UTC is used quite often to synchronize time across multiple time zones. The raw time data sent from GPS satellites is UTC. In my line of work, we use the time signals from GPS to sync our data collection…
Hi fenixuser that is a nice watch you are thinking of. UTC is based on 0 degrees longitude and is fixed throughout the year with no daylight saving. It has traditionally been used by navigators fixing their position with a sextant at 12:00 UTC. Given your watch has a GPS unit, you are unlikely to use it for this. UTC is also used for military and naval operations that may span several time zones. This saves any confusion about coordinating operations over a wide area. When used by the military, it is sometimes known as Zulu time. Have fun on your multi-time zone expeditions
The only time I have used it was on a long rail and air journey of 40 hours from southern Taiwan to northern UK.

For a normal person in Scandinavia, it may be less useful.
