John, Even if you want a procedure to calculate the EoT at a certain time at a certain day, what accuracy do you need? If 5 seconds is enough you could use the year formula calculated by my program equadecl. Use as input a decimal daynumber to get the wanted EoT but also correct for the longitude you are living. The basic output is for noon GMT.
If you need higher precision then look for another procedure. I also would like to know for what reason you need such a procedure in dialing. Fer.
