Unexpected delay while using clocks on TiRTOS

Tool/software: TI-RTOS

Hi,
  I am trying to setup a clock handle that will post a software interrupt every 10ms.
  BIOS_getCpuFreq() gives me the DSP frequency = 600MHz.

  I setup the clock with the given parameters :

    Clock_Params_init(&my_clk_params);
    my_clk_params.startFlag = TRUE;
    my_clk_params.period = 600000; //num_ticks_to_wait = 600000 600M ticks per second, hence 600000 ticks for 10ms delay?
    my_clk_params.arg = NULL;
    my_clk_handle = Clock_create(my_clock_handler, 100, &my_clk_params, NULL); // timeout value 100 not used as startFlag = TRUE ?

  I notice that the clock_handler fires off approximately every 7 minutes, instead of the expected 10ms.

  I configure the SWI as follows :

    Swi_Params_init(&my_swi_params);
    my_swi_params.arg0 = 0;
    my_swi_params.arg1 = 0;
    my_swi_params.priority = 1;
    my_swi_params.trigger = 1;
    my_swi_handle = Swi_create(my_swi_handler, &my_swi_params, NULL);
    
    Void my_clock_handler(UArg arg0)
    {
      Swi_post(my_swi_handle);
    }
    
    Void my_swi_handler(UArg arg0, UArg arg1)
    {
      sem_post(&my_semaphore);
    }

Did i miss anything while configuring the clock instance or software interrupt ?
