backendTimeOffsetMilliseconds

Time offset measured at the establishment of the real time connection to the Webcom back end between the running device clock and the Webcom back end clock.

If disconnected, this value is set with the last known offset if the connection has ever been established.

Possibles values are:

• null if the offset is not available (typically when the connection has never been established to the Webcom back end),

• A positive number if the back end clock is ahead of the device clock.

• A negative number means the back end clock is behind the device clock.
