The Enter command allows you to connect to your pod and take a lab on real equipment. If you reach this page 15 minutes or less before the lab starts, you will see a clock on the upper left that counts down to the lab start time. During the last 7-9 minutes of this countdown, the equipment is being set up for the lab that has been reserved. Once the countdown is over, the equipment is ready for that lab. A countdown of your remaining time to actually perform the lab then starts.
The clock time is listed using the web server's local time and is regularly updated via NTP so as to be very accurate.
