  • use jiffies and read that as CLOCK_MONOTONIC
  • use rt offset and read/write that as CLOCK_REALTIME and for [s|g]ettimeofday()

Where was CLOCK_MONOTONIC supposed to be defined in kernel space? I had to add an explicit define in sys.c because I cannot find any reference to that symbol in kernel code. Missing common header?

Time.h is nowhere to be found in kernel code. Is it a libc include? Libc include are ignored in kernel, as we compile with nostdinc.

it is in newlib. that flag seems gone, compiles and works fine this way. i agree we should split it off to frosted-headers though and include that both ways.

The stdinc problem is not only related to this. This issue can be closed, but the problem persists until we fix #121

Thanks
