Oxford time

Oxford time is the custom of having scheduled events occur five minutes past the specified time. It is a peculiar tradition of timekeeping in Oxford, especially in connection with the University of Oxford.[citation needed]
Astronomical background[]
As a result of the rotation of the Earth, the mean solar time of places that differ from each other in longitude deviates from one another; this deviation amounts to four minutes of time per degree difference in geographical longitude, or one hour per fifteen degrees.[citation needed] For a long time, it was common practice in different cities to actually use this local mean solar time as a basis for timekeeping, so that time differences between different cities could also form within one country. It was not until the 19th century that time zones were introduced, whereby a common legal time was defined for a larger area, such as a state.[1] In Great Britain the mean solar time at the Greenwich meridian was defined as the national standard, against which the mean solar time at Oxford is delayed by five minutes.[2]
Oxford time today[]
Out of tradition, local Oxford mean time is still used as a basis for many events in the city, as opposed to the more common Greenwich Mean Time (GMT) defined by the Greenwich meridian.[citation needed] The consequence of this is that, when measured a clock set to GMT, events begin five minutes after the specified time. This applies, for example, to lectures,[3] the closing of college doors[4]and services in Christ Church Cathedral.[5] Despite superficial similarities, the Oxford period, therefore, has a historical background that differs from that of the academic quarter used in some continental European universities.[6]
Unlike GMT, Oxford time observes British summer time, as civil time in the UK does. This means, for example, that during the period when summer time is in effect, a university lecture scheduled for 9:00 Oxford time would commence at 9:05 British Summer Time (BST), corresponding to 8:05 GMT.

In literature[]
Lewis Carroll, who himself taught at Oxford, took Oxford time as the inspiration for the perennially unpunctual White Rabbit in Alice's Adventures in Wonderland.[7]
