    time = float(camera.photo.meta['Exif/DateTimeOriginal'].split(" ")[1][:-3].replace(":", "."))
    time = time // 1 + (time  - time // 1) * 100 / 60
    time_table.append(time)
    #time_table.sort()
    print(time_table)
time_table.sort()
limits = (time_table[0], time_table[-1])
interval = 08.03
interval1 = 08.05
start = limits[0]
    #interval2 = interval + interval1
    #time = time // 1 + time  - time // 1
while True:
