The Papophoplon in 1 minute

Brief recap: 

Sundials indicate true solar time. 

There are three adjustements to convert it to the time on our watches (standard time):

1. Mean time
2. Standard time (the same hour for an entire territory) and
3. Daylight saving Time

The Papophoplon gives you those 3 adjustements for any day in the year.
