Hi guys.
The current SNTP contrib example has a set of macros to get and set the
time. If these macros are set to external functions, then the compiler
will complain because it doesn't know the prototypes; so the user has to
modify the sntp.c file.
What if sntp.c calls sys_gettime() and sys_settime(), which, the same as
for sys_now(), are system provided functions ?
Those functions can be:
void sys_gettime(u32_t *sec, u32_t *us);
void sys_settime(u32_t sec, u32_t us);
If the system does not handle microseconds, then they will just write as
0 and discard the us, respectively.

I can do it if you agree
