* 2^40 * 10^-9 / 60 = 18.3 minutes.

* SYSTIM is converted to real time using a timecounter. As
* timecounter_cyc2time() allows old timestamps, the timecounter
* needs to be updated at least once per half of the SYSTIM interval.
* Scheduling of delayed work is not very accurate, so we aim for 8
* minutes to be sure the actual interval is shorter than 9.16 minutes.
* timecounter_cyc2time() allows old timestamps, the timecounter needs

* Scheduling of delayed work is not very accurate, and also the NIC
* clock can be adjusted to run up to 6% faster and the system clock
* up to 10% slower, so we aim for 6 minutes to be sure the actual
* interval in the NIC time is shorter than 9.16 minutes.
