    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 automatically adjust for daylight saving time.
    Internal-Calendar Time Adjustment—Clocks with an internal calendar keep track of the current date and time to make daylight saving time changes. They must be manually set at startup.
    Ethernet Time Adjustment and Wi-Fi Time Adjustment—Wi-Fi and ethernet clocks link to your network for time updates so they can be synchronized with other clocks in your facility. To operate ethernet clocks, use a CAT5 or faster ethernet cable to connect the clock to your power-over-ethernet switch or to a power converter (sold separately).
    Radio Signal Time Adjustment—Radio signal clocks recalibrate their accuracy each day using a signal from the NIST atomic clock in Colorado. They’re also known as atomic clocks.
