In this link, for example,
first we see the date 2016-09-08- (8-September-2016)
then we have the hour 21- (9 PM)
after that we see the latitude and longitude of the zone of the world which we are looking at 42.472,6.680, (centered on Spain and France)
and last but not least, the zoom level 5 (Being 0 the less zoom and 17 the most zoom)
Hope I helped! :)
