An eruption by Mount Etna on the Italian island of Sicily on Saturday morning left a nearby airport closed. It also made many locals late for work.
According to reports, bemused Sicilians discovered that all their clocks were running 15 minutes fast.
It was noticeable when thousands of people arrived early to work.
The fast forward time keeping has affected a wide spectrum of digital clocks and watches – from computers through to alarm clocks.
Locals have also blamed aliens, poltergeists, solar explosions and electrical disturbances caused by underwater cables.
One theory is that perhaps there was a regional time shift or slip.
Anomalies in the Earth’s magnetic field are not unusual near volcanoes, due to the presence of piezomagnetic minerals under various strains and pressures.
However these fields have never altered time, or clocks in such a way before, which leads to a lot of speculation.
