Whats allowed in the Init() task

[Matthew J Fletcher]

Gedare,

Yes the "hello" example works fine. I just tried the "ticker" example, but
rtems_clock_set() returns RTEMS_INVALID_CLOCK. Odd, maybe the samples dont
get tested very often.

It _TOD_Validate() is rejecting the time set in the example, and i am
literally using the code from the example. Its returning false at the first
'if' test, the big one checking against the constants.

Is the test for 'the_tod->year < TOD_BASE_YEAR' correct given then are
equal at 1988 ?
