UTC

Abbreviation for Coordinated Universal Time. Basis for expressing worldwide time specifications. The UTC reference time is not a local time zone, but a general reference time based on atomic time standards , from which the times of all local time zones are derived. UTC is defined in such a way that it corresponds to Greenwich Mean Time (GMT). The UTC reference time differs slightly from Universal Time (UT1), which is linked to the rotation of the earth and where the mean solar day consists of 86400 seconds. By means of leap seconds, this difference is kept down to less than 0.9 seconds a year. In ABAP, UTC time specifications occur in conjunction with time stamps.
