The 581 series LED digital world time zone clocks have 10 character user changeable multi-color dot matrix LED displays that alternate between time, date and day of the week with white vinyl zone labels below. The 581 models can display 1 to 8 zones.
More zones may be displayed than physically available by page flipping to another set of zones – For example, a 5 zone display can actually display up to 20 zones by page flipping through 4 sets of zones. Selected zones can remain constant while other zones change.
You may choose between 12 or 24 hour time formats. Date formats include numeric, three character alpha-numeric month, day of month, day of week, day of the year, and four digit year.
