General
The time is incorrect
If the clock is off by a series of hours, in the command line type:
sudo dpkg-reconfigure tzdata
The R-Pi has no real-time clock, so unless it can access a timeserver over the network at
boot, or time is manually entered by the user, the time/date will restart counting from the
last logged time in the previous session.
A part broke off
The silver cylinder near the microUSB power input is a 220 uF capacitor ("C6" on
schematic). It sticks up and due to the small surface-mount pads, it is easy to break off;
several people have done so. This is a power supply filter capacitor which reduces any
noise and spikes on the input +5V power. If you like, you can solder it back on, or just
leave it off. If you do solder it back on, take care to observe the correct polarity with the
black stripe towards the board edge. This part, C6 is a "just in case" component which is
good design practice to include, but as it turns out (http://www.raspberrypi.org/phpBB3/
viewtopic.php?f=2&t=4926|) most power supplies still work OK without this part
installed. This part is also discussed here (http://elinux.org/
