The Lathem 6000E’s dot matrix printer can be easily programmed to print the time in 12-hour (AM/PM) or 24-hour format, as well as in regular minutes or 1/100 of an hour.  A programmable time table can be used to automatically shift between one of six columns across the card to accommodate additional break and overtime punches.  The day advance time is also user-defined allowing employees to work past midnight.  A built-in relay allows synchronized external bell ringing to indicate the start and stop of work periods and breaks.  Standard two color printing can be used to highlight tardy arrivals and early departures in red for quick time card auditing.  Unlike traditional time recorders, the 6000E never needs resetting following a power interruption, due to its lithium battery-backed memory.  An optional rechargeable battery also allows for full operation for 24 hours or 100 punches in case of a power failure.  The clock’s perpetual calendar changes the year, month, date, and even adjusts for daylight savings automatically.  The clock is accurate within 3 minutes per year.
