[time-nuts] 15 Seconds error...??

[lists at lazygranch.com]

I think the time jumps would be a problem for the GPS "customers". Suppose I am computing speed by differential readings. The jump would be an issue, especially if time went backwards. 

File stamps. Stock timing. Similar problems.

The way the GPS set of gears works, they need a continuous linear time 
internally. The UTC correction mechanism was added later.

It makes sense to create a unique internal time-scale and adjust to 
external time-scales later. It's not bad to have their own internal 
time-scale which one has control over, the key aspect lies in being able 
to relate it to other time-scales in a known and predictable fashion, if 
needed.
