Best approach for a 10 min extract out of several log files with timestamped records

I have a task where I need to code a shell script to extract a 10 min range (10 min from now until now) extract of a log file. I taught I could simply use a command that would say something like Start=date - 10 min but I didn't find anything. Looks like the only solution would have to code a...

function::ctime

FUNCTION::CTIME(3stap)					      Time utility functions					    FUNCTION::CTIME(3stap)

NAME

       function::ctime - Convert seconds since epoch into human readable date/time string

SYNOPSIS

	   ctime:string(epochsecs:long)

ARGUMENTS

       epochsecs
	   Number of seconds since epoch (as returned by gettimeofday_s)

DESCRIPTION

       Takes an argument of seconds since the epoch as returned by gettimeofday_s. Returns a string of the form

       "Wed Jun 30 21:49:08 1993"

       The string will always be exactly 24 characters. If the time would be unreasonable far in the past (before what can be represented with a
       32 bit offset in seconds from the epoch) an error will occur (which can be avoided with try/catch). If the time would be unreasonable far
       in the future, an error will also occur.

       Note that the epoch (zero) corresponds to

       "Thu Jan 1 00:00:00 1970"

       The earliest full date given by ctime, corresponding to epochsecs -2147483648 is "Fri Dec 13 20:45:52 1901". The latest full date given by
       ctime, corresponding to epochsecs 2147483647 is "Tue Jan 19 03:14:07 2038".

       The abbreviations for the days of the week are 'Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', and 'Sat'. The abbreviations for the months are
       'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', and 'Dec'.

       Note that the real C library ctime function puts a newline ('
') character at the end of the string that this function does not. Also note
       that since the kernel has no concept of timezones, the returned time is always in GMT.
