Description copied from class: ExternalResourceMillisecondStoreDataProvider

Loads an array of bytes from the specified location. This location is a concatenation of the base location and one of the extensions, depending on which of the values needs loading.

This method needs to return a binary stream from the specified location. This binary stream should encode the long values that represent the milliseconds. Each consecutive 8 bytes of the stream should correspond to an individual millisecond. This binary stream is then decoded into an array of longs. For the unix epoch offset, only a single long value (i.e. 8 bytes) should be returned in the binary stream.
