While consulting the online reference about gettickcount
https://www.freepascal.org/docs-html/rtl/sysutils/gettickcount64.html
I could not know anything about the units involved.
It says "It is useful for time measurements, but no assumtions should
be made as to the interval between the ticks."
I understand that in some cases the measure may deviate from the real
value but perhaps, at least the units, should be stated.
As a physicist by education, normally I'd agree with you about units,
but not in this case.
In this case I will not put it because it can/will depend on the system.
You should only use it for relative measurements, in that case the
unit does
not matter.
If so, why doesn't the *nix implementation return the full precision
rather than dividing to get in the ms range ?
I happened to run into this a few weeks ago, and considered it a mistake
(meaning the unit was fixed ms, and the remark refering to the update
granularity rather than unit).
