RTOS/CC2640R2F: How to use 64-bits time （time_t）

Part Number:CC2640R2F

Tool/software:TI-RTOS

Hi，all

I want to use 64-bits time in cc2640r2f with TI-RTOS .

The purpose is that I need to deal with the time after 2038-12-31 23:59:59.

I have simply added the "_DLIB_TIME_USES_64" and "_DLIB_TIME_ALLOW_64" definition to pre-processor in IDE (IAR for arm 8.22.2).

Then I built the project,it generated one error when doing post building action .

The xdc clock module is used.

I know the size of the seconds of "Seconds_set(UInt32 seconds);" is 32-bits.So I couldn't do any any changes to the xdc clock module.

So I use the clock module just as a timer-tick.,and add time offset (not from 1970) outside of seconds module.

Here is what I want to do:

Seconds_set(0);

t=time(NULL);

t+=(1514736000);// time start from 2018/1/1 0:0:0

ctime(&t);....

.....

If the time_t is 64-bits, it can work fine.

If the time_t is 32-bits, it will overflow after 2038.
