My hope is that this interface is simple enough and general enough to be usable by other RTC chips that may also support calibration, and that both design and code are of sufficiently quality to make it into the mainline at some point.
The M41T11 clock has a built-in power sense circuit which detects power failures and automatically switches to the battery supply during power failures.
The energy needed to sustain the RAM and clock operations can be supplied from a small lithium coin cell.
Please contact our sales support for information on specific devices. Who We Are Management. Obviously it won’t be perfect, as the temperature will be lower when the device is off than when it is being calibrated, but the crystal’s accuracy curve m41tt11 reasonably flat across the relevant temperature range.

The basic idea is that when the device is connected to the network and an accurate reference clock is available, a userland process will periodically measure the divergence between the reference clock and the RTC, set the RTC to the correct time and step the calibration register in the correct direction to compensate for the observed drift.
