Digital Time Clock Comes In All Sizes
Digital time clocks come in all sizes, shapes and descriptions. They are highly flexible and precise. Some are used to unify time systems over long distances, and others are used with online time systems for employee time and attendance records.
The light emitting diodes (LED) display the time in various colors (generally red, yellow, green, and blue) and patterns (circular, rectangular, and with analog clock like features such as seconds display). Some digital time clocks are programmable to display time, date, temperature, and messages in different cycles. Others display the time in different time zones.
New digital time clocks are tough and resilient. The average life of LED displays is 300,000 hours. Their display panels use non-glare lenses and have up to three times the brightness of older models. Thus, digital time clocks can be used outdoors on poles or with suspension or wall mountings with one or two-sided fixed displays or rotating displays. The casings are constructed from corrosion resistant steel and have toughened glass displays.
Modern GPS systems use satellites to run a master/slave network of clocks. The master clock is regulated by a GPS satellite system and then drives each connected slave clock system. Other master/slave configurations are available: Ethernet NTP, IRIG-B, CDMA (cell tower), PC, etc. Such systems eliminate inaccurate time and attendance issues. They are always split-second accurate. These systems have battery back-ups for periods when the master system fails.
One of the simplest digital time and attendance is the manual time punch clock using cards. These are easy-to-use, feature automatic printing, have easy-to-read displays, clear dot matrix printing, and desk or wall mountings. Many have two-color printing to identify late-comers or those who leave early by printing the time in red. Other benefits are increased production, enforced shift rules, accurate time records, and permanent proof of hours worked. Others use a code number for each employee or employees swipe a photo ID card with a magnetic strip through a reader.
More complex digital time clock and attendance systems are those that are network-based systems that automate time, attendance, job tracking, benefits and payroll functions. These systems are fully compatible with government, organizations, businesses, and school. They may be operated by these organizations networks or computers in real-time.
Some of the benefits of these systems are that they prevent unwanted overtime with e-mail alerts, prevent employee early clock-ins, and eliminate time cards and timesheet calculation errors. They provide convenient clocking and job tracking from a PC, a handheld PDA or telephone. These systems are compatible with known accounting and payroll programs such as QuickBooks, ADP, PayChex and many others.see it and check it from https://wamu.org/programs/morning_edition/15/12/22/as_aging_brains_internal_clock_fades_a_new_timekeeper_may_kick_in
Employees like digital and easy time clock systems because of the feedback they receive each time they clock in or out. The stations display the number of hours worked and remained non-overtime hours available. Managers like these systems because they can see the number of employee hours labored and jobs worked, absences, scheduled deviations, overtime alerts, and benefits paid for sick, vacation or PTO.
