    Keep accurate time—these clocks automatically adjust for daylight saving time.
    Calibration Certificate Traceable to NIST—Clocks with a NIST calibration certificate have been tested to NIST standards for accuracy.
    Internal-Calendar Time Adjustment—Internal-calendar clocks keep track of the current date and time to make daylight saving time changes. They must be manually set at startup.
    Ethernet Time Adjustment—Ethernet clocks receive power and time updates from your network, so they will automatically adjust for daylight saving time and can be synchronized with other clocks in your facility. Use a CAT5 or faster Ethernet cable to connect the clock to your Power over Ethernet (PoE) switch or to a power converter (sold separately).
    Radio Signal Time Adjustment—Radio-signal clocks are also known as atomic clocks. They use the NIST atomic clock in Colorado to adjust for daylight saving time. These clocks receive a daily signal to recalibrate for accuracy.

    These clocks save you time at the end of a pay period by automatically totaling each employee’s hours on their time cards. They print automatically when a card is inserted. The display shows the date, day of the week, and time (an internal calendar auto-adjusts for daylight saving time). Time cards are sold separately.
