Daylight savings time by continuous adjustment

Did you remember to set your cellphone's clock back an hour for daylight savings time?  Of course not!  It happens automatically.

World time is effectively synchronized.  You can schedule a zoom meeting over several continents and everyone will arrive within a minute.  This remarkable fact, which we take for granted, is a side-effect of advancements in communication technology.  In the last century, it could take 5-10 minutes to start a meeting with people in the same building.  

The problem with springing forward is that we suddenly lose an hour.   Does it have to be that way?  

Suppose the servers that set our cellphone clocks made continuous adjustments throughout the year.  Spread the one hour we need to lose in the spring over the course of the winter.  Days are a few seconds shorter in the winter, a few seconds longer in the summer.  

What about clocks that are not on the net?  Won't they go slowly out of sync?  Yes, but that already happens.  Unconnected timepieces are always suspect.  The only clocks you trust are on your networked devices.

The planet changes gradually.  Our clocks should too.
