Hi Folks

There does not appear to be any documentation about wallclocks. What
timezone should it return the time in? I assume its UTC? The code in
libc will then take care of any time zone offsets?

Is this correct?

It should be. Last time I checked, the stuff in libc did not exactly
behave as expected though.

Correct. Although I'm not sure it distinguishes between UTC and GMT well 
enough when it comes to DST offsets.

In what respect? That's what cyg_libc_time_setzoneoffsets() et al is for, 
the values of which are used by localtime().
