UTC Time
Click this option to see UTC time at the bottom right corner of the display
presentation.
Coordinated Universal Time (UTC) is a time standard based on International
Atomic Time (TAI) with leap seconds added at irregular intervals to
compensate for the Earth's slowing rotation. Leap seconds are used to allow
UTC to closely track UT1, which is mean solar time at the Royal Observatory,
Greenwich. The difference between UTC and UT1 is not allowed to exceed
0.9 seconds, so if high precision is not required the general term Universal
Time (UT) may be used. In casual use, Greenwich Mean Time (GMT) can
be considered equivalent to UTC or UT1 when fractions of a second are not
important.
