date — Returns the number seconds since a base date.


Returns the number seconds since a base date, using the operating system's clock. The base is 1 January 1970 for Csound using doubles, and 1 January 2010 for versions using floats.


ir date


ir -- value at i-time, of the system clock in seconds since the start of the epoch.

Note that the base date was originally 1970 but since verson 5.14 it has been changed as single precission floating point numbers are insufficient to indicate changes.


Here is an example of the date opcode. It uses the file date.csd.

      print ii
      Sa dates ii
      prints Sa
      Ss dates -1
      prints Ss
      St dates 1
      prints St 

i 1 0 1

Its output should include lines like this:

instr 1:  ii = 1165665152.000
