Please answer this: Extract the answer to the question from the following context. Question: What is a function of the concept? Context: In non-relativistic classical mechanics, Newton's concept of "relative, apparent, and common time" can be used in the formulation of a prescription for the synchronization of clocks. Events seen by two different observers in motion relative to each other produce a mathematical concept of time that works sufficiently well for describing the everyday phenomena of most people's experience. In the late nineteenth century, physicists encountered problems with the classical understanding of time, in connection with the behavior of electricity and magnetism. Einstein resolved these problems by invoking a method of synchronizing clocks using the constant, finite speed of light as the maximum signal velocity. This led directly to the result that observers in motion relative to one another measure different elapsed times for the same event.

Please answer this: Extract the answer to the question from the following context. Question: what is the last time of year mentioned? Context: The French Marines and naval infantry intended for the invasion of northern Germany were dispatched to reinforce the French Army of Châlons and fell into captivity at Sedan along with Napoleon III. A shortage of officers, following the capture of most of the professional French army at the Siege of Metz and at the Battle of Sedan, led naval officers to be sent from their ships to command hastily assembled reservists of the Garde Mobile. As the autumn storms of the North Sea forced the return of more of the French ships, the blockade of the north German ports diminished and in September 1870 the French navy abandoned the blockade for the winter. The rest of the navy retired to ports along the English Channel and remained in port for the rest of the war.

Context: Following the earthquake, donations were made by people from all over mainland China, with booths set up in schools, at banks, and around gas stations. People also donated blood, resulting in according to Xinhua long line-ups in most major Chinese cities. Many donated through text messaging on mobile phones to accounts set up by China Unicom and China Mobile By May 16, the Chinese government had allocated a total of $772 million for earthquake relief so far, up sharply from $159 million from May 14.
