When we enter the title of an article or book, we automatically add the date of the day, but how do we do it if we want to add the time of the computer to the document?
Solution:
With two macro packages providing the ability to print out time, the DateTime package and the Scrtime Pack offer different input options, such as 24-hour, 12-hour, and so on, readers can choose according to their own requirements.

Demo Code:
\documentclass{article}
\pagestyle{empty}
\SETCOUNTER{PAGE}{6}
\SETLENGTH\TEXTWIDTH{305.0PT}
\USEPACKAGE{CJK}
\usepackage{times}
\usepackage{datetime}
\usepackage{scrtime}
\begin{cjk}{gbk}{kai}
\begin{document}

Packages is available, both providing ranges of ways of printing the date, as well as of the time:this question would Concentrate on the time-printing capabilities, and interested users can investigate the documentation for details about D Ates.

The datetime package defines-time-printing functions: \xxivtime (for 24-hour time), \ampmtime (for 12-hour time) and \ Oclock (for Time-as-words, albeit a slightly eccentric set of words).

The Scrtime package (part of the compendious Koma-script bundle) takes a package option (12h or 24h) to specify how Times is to be printed. The command \thistime then prints the time appropriately (though there's no am or PM in 12h mode). The \thistime command also takes an optional argument, the character to separate the hours and minutes:the default is of Course:.

The current computer's time and date are:


\xxivtime \, \today

\ampmtime\, \today

\oclock\, \today

\thistime\, \today

\END{CJK}
\end{document}
