I think you are using the wrong tool. You appear to be using gnu coreutils, the "stat" command is available.
Filetimes (ctime, mtime, and atime plus and optional file "birth time") are kept in epoch seconds.
There are 86400 seconds in one day. stat -c "%X filename" returns that value for mtime for the file. mtime is the last time the file was written.
So there are lot of ways to do this. One way:
Code:
z=$(( 16 * 86400 ))
when=$(( `date +%s` - $z )) ## epoch seconds 16 days ago
for f in path/to/files/*
do
check=$(( stat -c "%X" $f ))
if [ $check -le $ when ]; then
ls -l $f
fi
done
The above assumes 86400 * 16 seconds from RIGHT NOW. If you want the entire day starting from midnight then you have to subtract the extra seconds after midnight

ROTATELOGS(8) rotatelogs ROTATELOGS(8)NAME
rotatelogs - Piped logging program to rotate Apache logs
SYNOPSIS
rotatelogs [ -l ] [ -f ] logfile rotationtime|filesizeM [ offset ]
SUMMARY
rotatelogs is a simple program for use in conjunction with Apache's piped logfile feature. It supports rotation based on a time interval or
maximum size of the log.
OPTIONS -l Causes the use of local time rather than GMT as the base for the interval or for strftime(3) formatting with size-based rotation.
Note that using -l in an environment which changes the GMT offset (such as for BST or DST) can lead to unpredictable results!
-f Causes the logfile to be opened immediately, as soon as rotatelogs starts, instead of waiting for the first logfile entry to be read
(for non-busy sites, there may be a substantial delay between when the server is started and when the first request is handled,
meaning that the associated logfile does not "exist" until then, which causes problems from some automated logging tools). Available
in version 2.2.9 and later.
logfile
rotationtime
The time between log file rotations in seconds. The rotation occurs at the beginning of this interval. For example, if the rotation
time is 3600, the log file will be rotated at the beginning of every hour; if the rotation time is 86400, the log file will be
rotated every night at midnight. (If no data is logged during an interval, no file will be created.)
filesizeM
The maximum file size in megabytes followed by the letter M to specify size rather than time.
offset The number of minutes offset from UTC. If omitted, zero is assumed and UTC is used. For example, to use local time in the zone UTC
-5 hours, specify a value of -300 for this argument. In most cases, -l should be used instead of specifying an offset.
EXAMPLES
CustomLog "|bin/rotatelogs /var/logs/logfile 86400" common
This creates the files /var/logs/logfile.nnnn where nnnn is the system time at which the log nominally starts (this time will always be a
multiple of the rotation time, so you can synchronize cron scripts with it). At the end of each rotation time (here after 24 hours) a new
log is started.
CustomLog "|bin/rotatelogs -l /var/logs/logfile.%Y.%m.%d 86400" common
This creates the files /var/logs/logfile.yyyy.mm.dd where yyyy is the year, mm is the month, and dd is the day of the month. Logging will
switch to a new file every day at midnight, local time.
CustomLog "|bin/rotatelogs /var/logs/logfile 5M" common
This configuration will rotate the logfile whenever it reaches a size of 5 megabytes.
ErrorLog "|bin/rotatelogs /var/logs/errorlog.%Y-%m-%d-%H_%M_%S 5M"
This configuration will rotate the error logfile whenever it reaches a size of 5 megabytes, and the suffix to the logfile name will be cre-
ated of the form errorlog.YYYY-mm-dd-HH_MM_SS.
PORTABILITY
The following logfile format string substitutions should be supported by all strftime(3) implementations, see the strftime(3) man page for
library-specific extensions.
o %A - full weekday name (localized)
o %a - 3-character weekday name (localized)
o %B - full month name (localized)
o %b - 3-character month name (localized)
o %c - date and time (localized)
o %d - 2-digit day of month
o %H - 2-digit hour (24 hour clock)
o %I - 2-digit hour (12 hour clock)
o %j - 3-digit day of year
o %M - 2-digit minute
o %m - 2-digit month
o %p - am/pm of 12 hour clock (localized)
o %S - 2-digit second
o %U - 2-digit week of year (Sunday first day of week)
o %W - 2-digit week of year (Monday first day of week)
o %w - 1-digit weekday (Sunday first day of week)
o %X - time (localized)
o %x - date (localized)
o %Y - 4-digit year
o %y - 2-digit year
o %Z - time zone name
o %% - literal `%'
