I recently purchased a heavily discounted E-PM2 from Newegg and low an behold the date and time are wiped every time the battery is removed to be recharged. The internal battery/capacitor must be shot. Not the end of the world but unacceptable for a brand new camera. My beef is with Olympus USA customer service. The immediate response from the tech agent was that this is completely normal. I told him that no camera I have owned in over 15 years had this defect. My Panasonics have no issue in this respect, nor does my friend who owns an E-M5. "Yup, completely normal". It took some pressing, quite a bit back and forth and me mentioning that the manual states that if the battery is removed for 24 h+ the date and time may be erased. I was put on hold, and then the agent returned and said that yes, this should not be happening and I should return the camera to Newegg (who has been fantastic, btw). Just a warning, and a supposition here but there's a chance the heavily discounted E-PM2s may have a high occurrence of this issue and Olympus's line is to tell owners to live with it.
