Djordje,

It's hsecs from v$timer, this is what the 'db reference' says:

V$TIMER
This view lists the elapsed time in hundredths of seconds. Time is measured since
the beginning of the epoch, which is operating system specific, and wraps around to
0 again whenever the value overflows four bytes (roughly 497 days).

regards,
Mario

Anybody knows what is the reference point for the timing used in the "tim"
column in the trace output, like in:

PARSE #3:c=0,e=0,p=0,cr=0,cu=0,mis=0,r=0,dep=0,og=4,tim=832261739
EXEC #3:c=0,e=0,p=0,cr=0,cu=0,mis=0,r=0,dep=0,og=4,tim=832261739

Apparently the scale is 100 per second for 8i and 976,562.5
(1,000,000,000/1024) for 9, but I am not quite clear what could be the
reference time (the time when counting of tim starts).  In different
databases I tried it, it is usually few months to a year back.

BTW, this column can be used if one needs to find out the exact time when a
query from the trace was run.

Thanks.

Djordje
