Technologies for timestamping data packets with forward error correction is disclosed. Alignment markers may be inserted in a data stream in order to assist with synchronization on the receiving end. After insertion of the alignment markers, a start of frame delimiter or other trigger may be detected, triggering a timestamp corresponding to the start of frame delimiter or other trigger. The data and the timestamp are sent to a remote compute device, which may timestamp the data before removing the alignment markers. With this approach, insertion of the alignment markers does not lead to a deviation in the timestamp of the sending compute device or the receiving compute device.
