The documentation is vague on purpose - due to the variety of platforms 
supported by FPC and the low-level nature of GetTickCount, we do not 
want to guarantee specific units (GetTickCount is supposed to be 
supported directly by the platform rather than having an additional RTL 
layer possibly unifying differences in platform behaviour on top of it).

BTW, it may be better to mention that you're not subscribed to the list 
unless you use different way for accessing the messages (like the list 
archive) because otherwise the responses may not reach you.
