I want to get the logical time so I can make the first instance of the object execute something while the rest do not execute.
Any suggestions as how to do this?

Logical time wouldn't work for that, as two objects in the same patch are created at teh same logical time. I'd suggest code like:
{ static int initted = 0; if (!initted) { .. this code only runs once .. initted = 1; } }

Hallo!
So you mean something like a singleton-pattern? Frank posted a (non-C) solution for that some time ago on the list ... (the thread was called "Symbols and Singletons")

Actually, I think logical time would work perfectly for what I am trying to do. I want to have the first instance that is executed in any given cycle run a function, but none of the rest. As far as I understand, the instance that is created first is not necessarily the first one to execute in each cycle.
So if I run the function, then set a global variable to the logical time, then next instance would check the logical time against that global variable. If it was equal, it would skip that function. That should guarantee that the first instance to execute in a given cycle will execute that function, rather than just using instance 0.
Any comments or suggestions appreciated, as usual. So... how do I get the logical time? Time to dig...

I guess I should really post some example code:
int timestamp;
hid_get_events(x) { // fill an array with the data that I get }
hid_read(x) { int right_now = get_logical_time(); if(right_now > timestamp) hid_get_events_into_array(x); hid_output_events_from_array(x); }

Oh... I get it. For that, the function is ugen_getsortno() -- returns an integer which increases eachtime DSP is restarted. You can add the function call (to the ugen chain for instance) each time you see ugen_getsortno() return an integer greater than the previous one you've seen.
