If you have a board without a battery then you might want to synchronize a date and time with your computer.
$ DATE=`date` ; ssh root@192.168.2.2 "TZ=America/Chicago date --set '$DATE' " ; echo "local: "; date ; echo "remote: " ; ssh root@192.168.2.2 " TZ=America/Chicago date "
Mon Jun 9 14:04:16 CDT 2014
local:Mon Jun 9 14:04:16 CDT 2014
remote:Mon Jun 9 14:04:16 CDT 2014
Note that output for Mac is CST and for Linux is UTC.
