This indicates that the date recorded for the last check on that filesystem is in the near future (49710 days is very nearly 232 seconds, so it looks like a signed 32-bit number is being interpreted as ungisned).
Looks like you have clock issues. It may be your BIOS battery dead. On the software side, compare
date outputs. You might need to set the hardware clock (using
hwclock tool for example), but first verify the battery state and replace if needed.
Edit: The issue looks to be well known. Google for "49710 days" "check forced" - it reveals links like this, or this one that clearly indicate the connection with system clock settings. The solution might be as simple as setting the hardware clock to UTC (as suggested in the second link), if the battery is ok.
