This article from the 1911 Encyclopaedia Brittanica describes methods for determining time, including two telegraphic longitude methods: http://23.1911encyclopedia.org/T/TI/TIME_MEASUREMENT_OF.htm George has already described one method, in which a single chronometer served both stations. In the other method each station had its own chronometer. The stations worked semi-independently, during the same time period if desired, and didn't have to observe the same stars. The telegraph link was used to compare clocks, but not to transmit meridian passages.
