Tiny RTC with alarm, battery switch-over, and I2C-bus
The correction is made by adding or subtracting clock correction pulses, thereby changing
the period of a single second but not by changing the oscillator frequency.
It is possible to monitor when correction pulses are applied. See Section 8.8.4.
8.8.1 Correction when OFFM = 0
The correction is triggered once every four hours and then correction pulses are applied
once per minute until the programmed correction values have been implemented.

8.8.2 Correction when OFFM = 1
The correction is triggered once every eight minutes and then correction pulses are
applied once per second until the programmed correction values have been implemented.
Clock correction is made more frequently in OFFM = 1; however, this can result in higher
power consumption.
