Secure context
This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
The PositionOptions.maximumAge property is a positive long value indicating the maximum age in milliseconds of a possible cached position that is acceptable to return. If set to 0, it means that the device cannot use a cached position and must attempt to retrieve the real current position. If set to Infinity the device must return a cached position regardless of its age.
Syntax
positionOptions.maximumAge = timeLength
