This is an announcement of a brand new application to RISC OS called TimeZones.
TimeZones gets information about various time zones from around the world and if they are in day light saving time, informs you when then start and finish daylight savings time. The difference between that time zone and GMT as well display the local time.
It requires a working internet connection and wget to work, with the data coming from the the World Time API site.
I have a short YouTube video of it in action for you viewing pleasure.
If you like my applications why not purchase some of my merchandise or donate some money to me through my Ko-Fi pages.
