# Timekeeper frequency estimates, as an absolute parts per million rate.
#
# Records a change to the estimated local oscillator frequency as calculated by
# Timekeeper for a particular time track. Values are expressed as utc parts
# per million monotonic parts, with 1,000,000 representing an oscillator that is
# running at exactly 1Hz. A value over 1,000,000 would indicate UTC is ticking
# faster than monotonic, i.e. Timekeeper is compensating for an oscillator that
# is running slow.
