I have done this long time back (probably 3 years now). I have almost forgotten syntax for each and everything.

with your sql statement from which you are generating a logfile in tmp directory. you can for surely save the result on another file. (don't know the syntax).

Then just put a normal command of date (take time out) and verify.. (by using awk / sed cut only the time column.

Not sure if this was helpful,

Time::ParseDate(3pm)					User Contributed Perl Documentation				      Time::ParseDate(3pm)

NAME
Time::ParseDate -- date parsing both relative and absolute SYNOPSIS
use Time::ParseDate; $seconds_since_jan1_1970 = parsedate("12/11/94 2pm", NO_RELATIVE => 1) $seconds_since_jan1_1970 = parsedate("12/11/94 2pm", %options) OPTIONS
Date parsing can also use options. The options are as follows: FUZZY -> it's okay not to parse the entire date string NOW -> the "current" time for relative times (defaults to time()) ZONE -> local timezone (defaults to $ENV{TZ}) WHOLE -> the whole input string must be parsed GMT -> input time is assumed to be GMT, not localtime UK -> prefer UK style dates (dd/mm over mm/dd) DATE_REQUIRED -> do not default the date TIME_REQUIRED -> do not default the time NO_RELATIVE -> input time is not relative to NOW TIMEFIRST -> try parsing time before date [not default] PREFER_PAST -> when year or day of week is ambiguous, assume past PREFER_FUTURE -> when year or day of week is ambiguous, assume future SUBSECOND -> parse fraction seconds VALIDATE -> only accept normal values for HHMMSS, YYMMDD. Otherwise days like -1 might give the last day of the previous month. DATE FORMATS RECOGNIZED
Absolute date formats Dow, dd Mon yy Dow, dd Mon yyyy Dow, dd Mon dd Mon yy dd Mon yyyy Month day{st,nd,rd,th}, year Month day{st,nd,rd,th} Mon dd yyyy yyyy/mm/dd yyyy-mm-dd (usually the best date specification syntax) yyyy/mm mm/dd/yy mm/dd/yyyy mm/yy yy/mm (only if year > 12, or > 31 if UK) yy/mm/dd (only if year > 12 and day < 32, or year > 31 if UK) dd/mm/yy (only if UK, or an invalid mm/dd/yy or yy/mm/dd) dd/mm/yyyy (only if UK, or an invalid mm/dd/yyyy) dd/mm (only if UK, or an invalid mm/dd) Relative date formats: count "days" count "weeks" count "months" count "years" Dow "after next" Dow "before last" Dow (requires PREFER_PAST or PREFER_FUTURE) "next" Dow "tomorrow" "today" "yesterday" "last" dow "last week" "now" "now" "+" count units "now" "-" count units "+" count units "-" count units count units "ago" Absolute time formats: hh:mm:ss[.ddd] hh:mm hh:mm[AP]M hh[AP]M hhmmss[[AP]M] "noon" "midnight" Relative time formats: count "minutes" (count can be franctional "1.5" or "1 1/2") count "seconds" count "hours" "+" count units "+" count "-" count units "-" count count units "ago" Timezone formats: [+-]dddd GMT[+-]d+ [+-]dddd (TZN) TZN Special formats: [ d]d/Mon/yyyy:hh:mm:ss [[+-]dddd] yy/mm/dd.hh:mm DESCRIPTION
This module recognizes the above date/time formats. Usually a date and a time are specified. There are numerous options for controlling what is recognized and what is not. The return code is always the time in seconds since January 1st, 1970 or undef if it was unable to parse the time. If a timezone is specified it must be after the time. Year specifications can be tacked onto the end of absolute times. If "parsedate()" is called from array context, then it will return two elements. On sucessful parses, it will return the seconds and what remains of its input string. On unsucessful parses, it will return "undef" and an error string. EXAMPLES
$seconds = parsedate("Mon Jan 2 04:24:27 1995"); $seconds = parsedate("Tue Apr 4 00:22:12 PDT 1995"); $seconds = parsedate("04.04.95 00:22", ZONE => PDT); $seconds = parsedate("Jan 1 1999 11:23:34.578", SUBSECOND => 1); $seconds = parsedate("122212 950404", ZONE => PDT, TIMEFIRST => 1); $seconds = parsedate("+3 secs", NOW => 796978800); $seconds = parsedate("2 months", NOW => 796720932); $seconds = parsedate("last Tuesday"); $seconds = parsedate("Sunday before last"); ($seconds, $remaining) = parsedate("today is the day"); ($seconds, $error) = parsedate("today is", WHOLE=>1); LICENSE
