Time clock. A time clock, sometimes known as a clock card machine, punch clock, or time recorder, is a device that records start and end times for hourly employees (or those on flexi-time) at a place of business. In mechanical time clocks, this was accomplished by inserting a heavy paper card, called a time card, into a slot on the time clock.
In 1979, Kronos delivered the world's first microprocessor -based time clock and, in 1985, delivered its first PC-based time and attendance product. In 1992, Kronos became a publicly-traded company on NASDAQ.
Watchclock. A watchclock is a mechanical clock used by security guards as part of their guard tour patrol system which require regular patrols.

Kronos is an operating system with time-sharing capabilities, written by Control Data Corporation in 1971. [1] Kronos ran on the 60-bit CDC 6000 series mainframe computers and their successors.
NOS ( N etwork O perating S ystem) is a discontinued operating system with time-sharing capabilities, written by Control Data Corporation in 1975. [2] NOS ran on the 60-bit CDC 6000 series of mainframe computers and their successors. NOS replaced the earlier CDC Kronos operating system of the 1970s.
CDC 6000 series. The CDC 6000 series is a discontinued family of mainframe computers manufactured by Control Data Corporation in the 1960s. [1] It consisted of the CDC 6200, [2] CDC 6300, CDC 6400, CDC 6500, [3] CDC 6600 and CDC 6700 [4] computers, which were all extremely rapid and efficient for their time.
The main marketing reason for its adoption was the development of its TELEX time-sharing feature and its BATCHIO remote batch feature. Kronos continued to use the COS/SCOPE 1 file system with the addition of a permanent file feature. An attempt to unify the SCOPE and Kronos operating system products produced NOS, (Network Operating System). [when?
