The Lathem date/time clock was easy to program and it works great for us. We purchased it to date/time stamp incoming documents. The product does what we need it to do and we are pleased with it.

Excellent product. I especially like the "atomic" time/date feature. The initial set-up instructions seemed a bit intimidating, but customer service was extremely helpful and made the process very easy.

Works pretty darn well. I was looking for an inexpensive unit to share between multiple agencies at our town hall (we do a very low volume) this works great, each office uses a different button and everyones happy. The month changes automatically as well which is really great.

We love this time stamp, we are a small town that does not have a lot of papers that need to be stamped, 3 departments are able to share this stamp, we each have our own button that prints our department name. The old timestamps you couldn't have more then one name on it but this one you can and it updates the month/date automatically.
