Just Curious.....

Hello All, I was just wondering if anyone knew why the real time clock in a micrologix 1100 increments the seconds by 2's. I had written a rung of logic to load some data at 23 hours 59 minutes and 59 seconds every night but it wasn't happening so when i went to investigate i noticed the seconds incrementing by 2's. No big deal, just wondering.

AB in the Knowledgebase doesn't explain why - just "that's the way it's supposed to work".

Yup, it has been talked about before. See link below.
