See, for source code and documentation,

 ftp://metalab.unc.edu/pub/academic/computer-science/history/pdp-11/codar/

You'll find the original distribution files (from README.1ST):

  The Model 120 Calendar Clock Source Kit contains:

   1) files to build the programs STIME and RTIME, which set the calendar clock
     and initialize your operating system's date and time, respectively,

        RTIME . COM RT11/TSX-Plus command file
        STIME . MAC Source for STIME for all RT11/TSX-Plus systems
        RTIME . MAC Source for RTIME for RT11 V4.0 and later (and TSX-Plus)

   2) subroutines used by RTIME and STIME to read and set the calendar clock,

        CCSUBS . MAC Source for subroutines used by RTIME

as well as the file CODAR.DIFF, which has the Y2K patches I did a few
years back to the sources.

Now that you've got TCP/IP working under RT-11, I'll also post my
"NBSTIM" source - it goes out and queries a National Bureau of Standards
time server for current UTC time and date over the network, converts it to
local time, and uses it to check or set the -11's clocks.
