data(exses)
x <- exses$stat$time - 304*(24*3600)
plot(x, x, type = 'l')
lines(x, floorPOSIXct(x, '2days'), col = 'blue', type = 's')
# To force the cut to occur on the 1st January
lines(x, floorPOSIXct(x, '2days', '1d'), col = 'lightblue', type = 's')
lines(x, floorPOSIXct(x, 'days'), col = 'red', type = 's')
lines(x, floorPOSIXct(x, '0.5d'), col = 'green', type = 's')
