A sequence of events is isochronous if the events occur regularly, or at equal time intervals. The term isochronous is used in several technical contexts, but usually refers to the primary subject maintaining a constant period or interval (the reciprocal of frequency), despite variations in other measurable factors in the same system.
The result displays text representing the time interval from date1 to date2 (date2 − date1). Dates are UTC—local times and time zones are not supported. Dates are checked for validity. For example, 29 February 2000 is accepted, but 29 February 1900 is not a valid date. Each date can include an era or a time, and a variety of formats are ...
time interval [3] as an object – part of the time axis limited by two instants. Being an object, it has no value; duration [4] as a quantity characterizing a time interval. [5] As a quantity, it has a value, such as a number of minutes, or may be described in terms of the quantities (such as times and dates) of its beginning and end.
