Might be that it means, if you use this you can start working at 8am and you are done by 2pm, while the others stay until 5.

On a more serious note.
IEEE 802 Committee
In February of 1980 the IEEE (Institute of Electrical and Electronics Engineers) formed a committee to establish standards for local area network communication.
The committee's identifying number reflects the year and month that it was created, "80" - "2". A number of separate committees have been formed, each responsible for developing standards in different areas of technology. Of particular interest are the 802.11 committee (with a number of separate working groups) for wireless standards, the 802.1 committee for device interaction and security, and the 802.3 committee for Ethernet networking.
