timek — Read absolute time in k-rate cycles.
timek is for time in k-rate cycles. So with:
sr = 44100 kr = 6300 ksmps = 7
then after half a second, the timek opcode would report 3150. It will always report an integer.
timek can produce a k-rate variable for output. There are no input parameters.
timek can also operate only at the start of the instance of the instrument. It produces an i-rate variable (starting with i or gi) as its output.
Here is an example of the timek opcode. It uses the file timek.csd.
Example 461. Example of the timek opcode.

Its output should include lines like this:
k1 = 1.000000 samples k1 = 2205.000000 samples k1 = 4410.000000 samples k1 = 6615.000000 samples k1 = 8820.000000 samples
