I got my shield a few weeks ago and after assembling deployed it for a week.
I had one major issue: time wasn't kept when I unplugged the shield. I checked the battery and it was over 3V. What else is easy to check to locate the issue?
Also, at some point I unplugged the shield, removed the SD card, copied the data, and then put the card back in (without modification). I was hoping that the logging would pick up where it left off but it didn't . I will reexamine the code (this is more within my skill set than the first problem) but I was wondering if someone could tell me how/why this happened right off the bat. I did connect the LEDs and have them blinking now so at least I will notice if this problem happens again.

Re: Datalogging Shield
perform the RTC tests to determine what could be the issue with the RTC
the default logging sketches make a new file for each power up, this is the safest way of logging, so that new files dont get overwritten.

Re: Datalogging Shield
I tested with the RTC sketches and my principal problem remains: time isn't counted when unplugged.
Sure, when I upload a sketch the time is set, but it's not ticking time away when not powered.
