No, it just shifts the problem to needing to know which are the working hours at each location you want to interact with. Timezones and Daylight Saving are completely different issues that appear related. Both have flaws, but at least local timezones are a sensible abstraction for general societal behaviour in a given location.

If you want a fixed standard time, we already have UTC, - get used to it and the offset of the _local_ times you need to know.
