You can use the fancyhdr and datetime package to help with this, as demonstrated in the following MWE.

Note that \today is actually defined in LaTeX (no extra packages needed), but you need datetime for \currenttime

\documentclass{article}
\usepackage{lipsum}
\usepackage{fancyhdr}
\usepackage{datetime}

\fancyhf{}
\fancyfoot[L]{\today\ \currenttime}
\pagestyle{fancy}

\begin{document}

\lipsum

\end{document}

This generates the following footer.

The fancyhf command clears the header and the footer, and the fancyfoot command does the specific part of your question. Setting the pagestyle as fancy seals the deal.

One can use \today to get the current date, the command \currenttime from datetime package to get the current time, and fancyhdr package to add it to every page.

[Tex/LaTex] Write date, time, and time zone

You can get the offset from GMT using the pdfTeX primitive \pdfcreationdate: (no doubt LuaTeX has something similar)

\documentclass{article}
\begin{document}
\def\grabtimezone #1#2#3#4#5#6#7#8#9{\grabtimezoneB}
\def\grabtimezoneB #1#2#3#4#5#6#7{\grabtimezoneC}
\def\grabtimezoneC #1#2'#3'{sign: #1 / hr: #2 / min: #3}
\expandafter \grabtimezone\pdfcreationdate
\end{document}

If you need to convert this into a timezone string, you'll need to define a dictionary of timezones to match up with the time offsets. Since I think this is a many-to-one mapping for many time zones, I'm not sure how that would work.

Once you work out exactly what you need for your application, I suggest writing to the datetime author to add such a feature to that package.

Update. To get a crude lookup table for getting string output for the timezone, you can try something like this:

\makeatletter
\@namedef{timezone+0930}{CST}
\@namedef{timezone+1000}{EST}
\@namedef{timezone+1030}{CST'}% daylight savings
\def\grabtimezone #1#2#3#4#5#6#7#8#9{\grabtimezoneB}
\def\grabtimezoneB #1#2#3#4#5#6#7{\grabtimezoneC}
\def\grabtimezoneC #1#2'#3'{%
  \@ifundefined{timezone#1#2#3}
    {No timezone for `#1#2#3'}
    {\@nameuse{timezone#1#2#3}}%
}
\def\timezone{\expandafter\grabtimezone\pdfcreationdate}
\makeatother

\timezone
