I needed an HTML select for every Timezone and really couldn’t find what I was looking for. Here is an abbreviated version so you know what I’m talking about:

Abbreviated HTML Select of Timezones

A smaller HTML select with timezones which maybe a good starting point in the USA.

<select id="timezone" name="timezone" class="custom-select">
  <option value="Pacific/Honolulu">Pacific/Honolulu GMT-10:00</option>
  <option value="America/Anchorage">America/Anchorage GMT-9:00</option>
  <option value="America/Los_Angeles">America/Los_Angeles GMT-8:00</option>
  <option value="America/Boise">America/Boise GMT-7:00</option>
  <option value="America/Denver">America/Denver GMT-7:00</option>
  <option value="America/Phoenix">America/Phoenix GMT-7:00</option>
  <option value="America/Chicago">America/Chicago GMT-6:00</option>
  <option value="America/Detroit">America/Detroit GMT-5:00</option>
  <option value="America/New_York">America/New_York GMT-5:00</option>
</select>

Abbreviated HTML Select of Timezones in Action

What I especially liked about the value field here is it standard across platforms and programming languages. The reason is because this the value field if from the tz database. Other values you will see for the HTML option have offsets and all sorts of different ideas. These usually fail because when dealing with time one has to account for the dreaded Daylight Savings Time.

I will now belabor the point of how going with the tz database value is the way to go by showing it in many different programming languages and finally in Unix.

Setting the Timezone in Javascript

new Date().toLocaleString("en-US", {timeZone: "America/New_York"})

Setting the Timezone in Java

Here we use ZonedDateTime which is highly recommended.

Long now = Instant.now().toEpochMilli();
ZonedDateTime zdt = toZonedDateTime(ts.toInstant(), "America/New_York");

Setting the Timezone in Python

>>> import os, time
>>> time.strftime('%X %x %Z')
'06:39:29 01/31/20 MST'
>>> os.environ['TZ'] = 'America/New_York'
>>> time.tzset()
>>> time.strftime('%X %x %Z')
'08:39:29 01/31/20 EST'
>>>

Setting the Timezone in GoLang

loc, err := time.LoadLocation("America/New_York")
if err != nil {
    // handle error
}

t := time.Now().In(loc)

Setting the Timezone in Perl

use POSIX qw(tzset);

$ENV{TZ} = 'America/New_York';
tzset;

my $now = localtime;
print "It is now   $now\n";

Setting the Timezone in Unix

$ tzselect
....
Therefore TZ='America/New_York' will be used.
$

Ok you get the point by now using the tz database for the value of the option in the HTML select is the way to go. Now here is some Java to generate an HTML select with all the timezones.

Java Code to Create a HTML Select of All Timezones

Running this code will pull from the Java SDK the timezones in the tz database. We can use it go generate an HTML select.

import java.util.TimeZone;

public class JavaScriptTimeZoneSelect {

  public static void main(String[] args) {
    String[] tzStrings = TimeZone.getAvailableIDs();
    System.out.println("<select id=\"timezone\" name=\"timezone\">");
    for(int i=0; i<tzStrings.length; i++) {
      TimeZone tz = TimeZone.getTimeZone(tzStrings[i]);
      String displayName = tz.getDisplayName();
      String name = tzStrings[i];
      Integer offset = tz.getRawOffset();
      Double offsetF = offset.doubleValue();
      offsetF = offsetF / 1000.0 / 60.0 / 60.0;

      String str = "GMT";
      if(offset>=0) str = "GMT+";

      Long offsetHours =  Math.round(Math.floor(offsetF));
      Double offsetMinsF = offsetF - Math.floor(offsetF);
      Long offsetMins = Math.round(Math.floor(offsetMinsF*60.0));

      String f = "  <option value=\"%s\">%s %s%d:%02d</option>";
      System.out.println(String.format(f,name,name,str,offsetHours,offsetMins));
    }
    System.out.println("</select>");
  }

}

When this Java code is run it will output the full list. Note, this list is meant to be pruned and/or guessed in some way. Presenting this full list to a user would be overwhelming.

Full List of HTML Select of Timezones in Action

Behold the full, overwhelming, crazy, way-to-long list of timezones in a single HTML Select. It gives you of something to work with and trim down.
