It seems that for Environment.TickCount mono returns basically the same
thing as it returns for DateTime.Ticks.
Environment.TickCount's icall looks like this:
res = (gint32) gettimeofday (&tv, &tz);
if (res != -1)
res = (gint32) ((tv.tv_sec & 0xFFFFF) * 1000 +
(tv.tv_usec / 1000));
return res;
while the DateTime_GetNow icall does this:
if (gettimeofday (&tv, NULL) == 0) {
res = (((gint64)tv.tv_sec + EPOCH_ADJUST)* 1000000 +
tv.tv_usec)*10;
return res;
}
These are rather more similar than makes sense, in any case.
Anyway, Environment.TickCount is documented by MS (at
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemEnvironmentClassTickCountTopic.asp)
as "containing the amount of time in milliseconds that has passed since the last time
the computer was started". I think mono's implementation should probably do something
similar, although I'm not yet sure what the correct way to do that something similar
would be.
