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

Below string matches the date format that I have it in logs but awk not working

Code:
$date +"<%b%_d, %Y,%l:%M:%S,%3N %p %Z>"

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'

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.
