Description

This class has no correlate in StationXML, but it is used for important documentation purposes in obsinfo, and thus is included as a comment in StationXML. It documents the addition or subtraction of leap seconds to the signal data, and any kind of clock drift. As is well known, OBS equipment does not have a GPS connection and its clock must be manually synchronized.
