More like 60 seconds per minute, 60*60 seconds per hour,
60*60*24 hours per day, 60*60 *24*365.25 seconds per year
which is one orbit of the Earth around the sun per orbit of the Earth
around the sun.
If anyone can find the equator lagging behind the pole to satisfy
Einstein's "Thence we conclude that a balance-clock at the equator
must go more slowly, by a very small amount, than a precisely similar
clock situated at one of the poles under otherwise identical
conditions" then I'll be convinced that time passes more slowly at the
equator, because all the evidence points to the pole completing an
orbit in exactly the same time as the equator and the Earth keeping
it's shape.
