Brave day sunk in hideous night

From Sonnet 12 by William Shakespeare:

When I do count the clock that tells the time,
And see the brave day sunk in hideous night;
When I behold the violet past prime,
And sable curls all silvered o'er with white;
When lofty trees I see barren of leaves
Which erst from heat did canopy the herd,
And summer's green all girded up in sheaves

British Summer Time is officially over for another year...
