Agree totally, only problem is, imo, the browser experience, even for well built web apps, is 'usually' subpar or more problematic or poor performing than a desktop app.
Seconds should be made to have a different duration depending on the time of day and year the second is ticked. This would happen in a way to facilitate a sunrise and sunset to occur at the same time every day of the year.
Sounds like its something that probably happens a lot and will continue to happen a lot?
