    Bash provides the -nt comparison operator which returns true if one file is newer than another file. Here's a script which illustrates this functionality

    #!/bin/bash

if [[ "$1" -nt "$2" ]]
then
    echo "$1 is newer than $2 - copying $1"
    #do something
else
    if [[ "$2" -nt "$1" ]]
        then
            echo "$2 is newer than $1 - copying $2"
            #do something
        else
            echo "$1 and $2 are the same time"
            #do nothing
        fi
fi

  2. Maybe the option -newer of "find" can do it.

    find . -newer directory -exec cp {} /new/location \;

  3. To set datetime components to shell variables:

    eval $(date "+day=%d month=%m year=%Y hour=%H min=%M secnd=%S")

    To compare dates, Iain's answer is the way to go.
