18f26j53 rtcc

I was surprised at the ease of use and accuracy of the RTCC. I am sending the time to line 1 and the day of week, month, and year to line 2. (2x20 LCD) I have compared the clock to the laptop time for a 2 week period and it's off by about 2 seconds. Ok for me. Question: I noticed the seconds count once in awhile will "skip" a second and show the next second instead. I believe what is happening is the RTCC clock (32Khz watch xtal) and the main program clock get out of sync (maybe in sync) and there is a conflict at rollover time. Maybe I need to add polling for the RTCSYNC bit and then read the data registers? The code I am using is from a previous post (Bruce-Rentron) with modifications for LCD use. I would like to also setup the clock with the deep sleep mode. Cheers JC
