Actually the Julian calendar started at noon, the 0.5 is added to get to
midnight. The Julian calendar was developed for astronomers, who view the

When using WaitFor() , ResetEvent and SetEvent as a semaphore , if a thread
is using BlockWrite() and the execution of BlockWrite() is conditional on
WaitFor() , will BlockWrite() continue to function after it is called once
MySemaphore.ResetEvent is called ?

I just noticed that the definition of the constants have 0.5 in it.
Why?
from dateh.inc
const
JulianEpoch = TDateTime(-2415018.5);
UnixEpoch = JulianEpoch + TDateTime(2440587.5);
