Re: [SR-Users] Computing a time difference when handling a stateless SIP request

Thanks! Looking at src\modules\pv\pv_time.c, it seems TV functions just use "gettimeofday". I was looking for a time difference based on a monotonically increasing clock (to avoid possible NTP drifting imprecision). I've looked at the "benchmark" module which seems to do something like that, but I don't think I can use it for what I need... Anyhow, I have another question. Using the TV I've come up with the following. This works, except that I don't know how to convert an int to a string padded with zeroes (e.g. 51 => "051"). Is there a transformation that allows to do that? $var(start_time) = $TV(Sn); # allows to cache $TV(s) and $TV(u) (...) $var(end_time) = $TV(Sn); $var(end_s) = $TV(sn); $var(end_us) = $TV(un); $var(diff_us) = $var(end_us) - $TV(u) + (1000000 * ($var(end_s) - $TV(s))); # convert this to ms (integer part) and us (fractional part) $var(diff_ms) = $var(diff_us) / 1000; $var(diff_us_f) = $var(diff_us) - (1000 * $var(diff_ms)); $var(diff_ms_us) = $var(diff_ms) + "." + $var(diff_us_f); # need to format on 3 digits... can we do the equivalent of sprintf("%03u") somehow ?
