times — Read absolute time in seconds.
Time in seconds is available with times. This would return 0.5 after half a second.
times can both produce a k-rate variable for output. There are no input parameters.
times can also operate 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 times opcode. It uses the file times.csd.
Example 462. Example of the times opcode.
See the sections Real-time Audio and Command Line Flags for more information on using command line flags.

Its output should include lines like this:
k1 = 0.000227 seconds k1 = 0.500000 seconds k1 = 1.000000 seconds k1 = 1.500000 seconds k1 = 2.000000 seconds
