How to convert from Ticks to date&time?

[David]

We only know the system ticks count, but we have no date or time function.

So we need the source code about solving the problem. I have googled several
times and no good results. can u help me?

Thanks in advance.

CLOCKS_PER_SEC might be useful. Bear in mind that system ticks may not
represent wall-clock time, but CPU time.

Once you have it in seconds, the rest is easy.

Unless you have a system function which quotes tick rate, you must use a
test loop to calibrate it yourself.

If you don't have a C implementation sufficient to provide time of day
information, you are far outside the scope of the newsgroup.

A "freestanding environment" (section 5.1.2.1) need not
provide a complete library implementation.

The O.P.'s fundamental problem is that he hasn't specified
what a "system tick" is. If it's a regularly-changing count
with a known zero point, conversion to human-readable form is
fairly straightforward. If it's a regularly-changing count
whose zero is not fixed (e.g., "most recent power-up"), the
conversion is impossible without further information. If it's
some more exotic quantity ("number of instruction issues since
power-up"), the conversion may be impossible altogether.

So, O.P.: What's a "system tick?" Something that carries
"system Lyme disease?"

Probably related to a network leech...
