Comparing different time formats

I am trying to do a comparison of files based on their last modified date.

I am pulling the first file from a webapp folder using curl.

Code:
curl --silent -I http://localhost:8023/conf/log4j2.xml | grep Last
Last-Modified: Tue, 22 Mar 2016 22:02:18 GMT

The second file is on local disk.

Code:
stat /var/tmp/log4j2.xml  | grep Modify | awk '{print $2" "$3}' | cut -d'.' -f1
2016-03-24 13:56:51

Is there a mechanism to convert the times ? So that I can then compare the two times and take an action accordingly.

NAME
zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
