Abstract
A method for synchronising a clock of an electricity meter which includes a first processing unit including a first port arranged to be connected to an external apparatus, having the following steps: receiving, via the first port, a first frame containing a reference time; configuring the first port to operate in an interrupt-triggering mode; receiving, via the first port, a pulse that specifies a synchronisation time, and triggering an interrupt that leads to the reference time being recorded as a current time at the synchronisation time; reconfiguring the first port so as to communicate via the first port using the serial link.
