I needed to write a similar service for our intranet to list the time at different installations world wide, knowing only their offset from UTC and whether or not they observe DST. DST occurs at the same time everywhere in the US, if it is observed.

I decided to just use one of the NIST time servers and a file with the offset, bool data

You can get the data by making a simple tcp call to the time server, which returns a string that you can split and compute the current time if you know the UTC off set.

Some more DST information, including what US territories, states and holdings acknowledge it.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
