Code:
#!/bin/bash to=`date +"<%b%_d, %Y,%l:%M:%S,%3N %p %Z>"` let from_in_seconds=`date +%s`-5000 from=`date -d @$from_in_seconds +"<%b%_d, %Y,%l:%M:%S,%3N %p %Z>"` awk '$0>=from && $0<=to' from="$from" to="$to" file.log
Code:
$date +"<%b%_d, %Y,%l:%M:%S,%3N %p %Z>" <Feb12, 2019, 1:36:55,448 PM UTC>
below string provide the dates past 30 minutes but while using it in awk it won;t work.
Code:
date --date='30 minutes ago' -u '+%b%_d, %Y, %T,%3N %p %Z' Feb12, 2019, 13:13:03,306 PM UTC

yes, <data> keep logging from the application regularly day and night in ascending order. Although, I am least concerned about the avoiding the date format (2019-02-12T12:26:59.842+0000: 45.152) but would like to have lines pulled when string matches that are from last 30 minutes only which has below date format.

nwfstime
NWFSTIME(1) nwfstime NWFSTIME(1) NAME
nwfstime - Display / Set a NetWare server's date and time SYNOPSIS
nwfstime [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ] [ -s ] DESCRIPTION
nwfstime displays a NetWare server's date and time. You can also set a NetWare server's date and time from the local time. OPTIONS
-h With -h nwfstime prints a little help text. -S server is the name of the server you want to use. -U user user is the user name to use for login. To set the server's time, you need supervisor privileges. -P password password is the password to use for login. If neither -n nor -P are given, and the user has no open connection to the server, nwfstime prompts for a password. -n -n should be given if no password is required for the login. As you need supervisor privileges for setting the date and time, this option is probably not used very often. -C By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off this conversion by -C. -s With -s, nwfstime sets the file server's date and time according to the local date and time. nwfstime 12/10/1996 NWFSTIME(1)
