1. A computing system comprising:

  • a first counter configured to operate at a first frequency and increment a first count value, wherein the first counter operates in a first energy mode;

    a second counter configured to operate at a second frequency and increment a second count value, wherein the second counter is configured to operate in a second energy mode and wherein the second frequency is different than the first frequency;

    a non-volatile machine-readable memory configured to store one or more event data; and

    a processor configured to;

    determine a first current time value based upon at least one of the one or more event data comprising switching of energy modes between the first energy mode and the second energy mode in the computing system and at least one of the first count value and the second count value selected based on the switching; and

    synchronize the first current time value with a second current time value upon determining that the second current time value is within a predetermined range of the first current time value.
