Abstract
A method and network for time synchronization of at least one master and at least one slave, which is an interrupt-capable network component. A time offset between a master time and a slave time is determined. A first time fraction of the determined time offset is adjusted in first synchronization step(s) using a time jump. The first time fraction corresponds to an integer multiple of the cycle duration of the interrupt(s) and a second time fraction of the determined time offset is adjusted in a number of successive second synchronization steps using frequency alignment and/or a time jump. The second time fraction corresponds to a non-integer multiple from the range ]−1.0[ and ]0.1[ of cycle duration of the interrupt(s). In each of the number of second synchronization steps, an actual occurring cycle duration of the interrupt(s) deviates from the predefined cycle duration by no more than a predefined deviation.
