The user is able to define a time offset for the displayed map. This can be useful for comparing multiple forecast times for one map. For the initial map, the time is defined as described in the ”First Navigation” section. Then, the time offset for each map can be individually specified on the top of the Layer Stack in the respective box. The time offset is given in hours and minutes. Use the time slider at the bottom to navigate the same amount of time forward or backward in time on all maps, while keeping the defined time offset constant.
