You will need an eCos wallclock driver for your hardware platform. You
will also need to ensure that the Wallclock I/O package
(CYGPKG_IO_WALLCLOCK) and the ISO C date and time package
(CYGPKG_LIBC_TIME) are part of your eCos configuration. You can then
call the time() function within the eCos C library to obtain calendar time.

I hope this helps

Are you getting 1 Jan 1970? 

Does your board actually know the time? 
Does it have a battery backed up real time clock?
Do you have the drivers necessary to access it? This often means I2C
drivers and a specific driver for the RTC hardware.

Date Time ? What sort of? Look at this:

	diag_printf("\n%s() of %s %s", __func__,  __DATE__, __TIME__);


The three arguments are strings that are generated during compilation of a  
module. So even after linking, each module "knows" when it was compiled.
