Question

我已经阅读了很多关于时刻时区的帖子，但我还是没有找到明确答案：

我的应用程序遍布全球，无论浏览器的时区如何，我总是希望显示日期和时间。时间为EST或EDT，以当时有效（“America / New_York”）为准。 moment-timezone.js是否只需要加载America / New_York的数据，因为这是我想要显示的唯一时区，或者我是否需要所有时区的数据，其中用户可能需要按时区顺序能够从那个时区转换为America / New_York？我需要能够从任何时区转换，因为当新用户加入时，我无法事先知道他们（及其浏览器）的时区。

现在我正在使用moment-timezone-with-data.js，但它是190KB。在这一点上，我想我宁愿做一个快速的AJAX请求并得到日期＆amp;来自服务器的时间 - 很容易在PHP中获得所需时区的当前日期/时间。

Answer 1

简而言之，如果你想做的只是将一些任意时刻转换为该时区，你只需要Am / NY，因为对moment（）的调用将产生一个对应于'UTCtime + local offset'的对象。只要你知道UTC的时间，你就不在乎它是什么。您从Am / NY tz数据获得的是哪个偏移现在适用于UTC时间以获得Am / NY时间。

Answer 2

您需要在应用程序中明确使用的每个区域的区域信息。

如果您只想在

 function pagination() {
     if( is_singular() )
            return;
     global $wp_query;
       /** Stop execution if there's only 1 page */
     if( $wp_query->max_num_pages <= 1 )
         return;
       $paged = get_query_var( 'paged' ) ? absint( get_query_var( 'paged' ) ) : 1;
          $max   = intval( $wp_query->max_num_pages );
                  /** Add current page to the array */
       if ( $paged >= 1 )
            $links[] = $paged;
            / ** Add the pages around the current page to the array */
       if ( $paged >= 3 ) {
            $links[] = $paged - 1;
            $links[] = $paged - 2;
        }

        if ( ( $paged + 2 ) <= $max ) {
            $links[] = $paged + 2;
            $links[] = $paged + 1;
        }

    echo '<div class="navigation"><ul>' . "\n";
    /** Previous Post Link */
    if ( get_previous_posts_link() )
        printf( '<li>%s</li>' . "\n", get_previous_posts_link() );
    /** Link to first page, plus ellipses if necessary */
    if ( ! in_array( 1, $links ) ) {
        $class = 1 == $paged ? ' class="active"' : '';
        printf( '<li%s><a href="%s">%s</a></li>' . "\n", $class, esc_url( get_pagenum_link( 1 ) ), '1' );

        if ( ! in_array( 2, $links ) )
            echo '<li>…</li>';

}



/** Link to current page, plus 2 pages in either direction if necessary */
    sort( $links );
    foreach ( (array) $links as $link ) {
        $class = $paged == $link ? ' class="active"' : '';
        printf( '<li%s><a href="%s">%s</a></li>' . "\n", $class, esc_url( get_pagenum_link( $link ) ), $link );
    }

    /** Link to last page, plus ellipses if necessary */

    if ( ! in_array( $max, $links ) ) {
        if ( ! in_array( $max - 1, $links ) )
            echo '<li>…</li>' . "\n";
        $class = $paged == $max ? ' class="active"' : '';
        printf( '<li%s><a href="%s">%s</a></li>' . "\n", $class, esc_url( get_pagenum_link( $max ) ), $max );
    }



    /** Next Post Link */

    if ( get_next_posts_link() )
        printf( '<li>%s</li>' . "\n", get_next_posts_link() );   
        echo '</ul></div>' . "\n";
}

时区内Adding，

parse moment objects America/New_York区就足够了。

例如：

＆＃13;

America/New_York

＆＃13;

moment.tz.add("America/New_York|EST EDT EWT EPT|50 40 40 40|01010101010101010101010101010101010101010101010102301010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010|-261t0 1nX0 11B0 1nX0 11B0 1qL0 1a10 11z0 1qN0 WL0 1qN0 11z0 1o10 11z0 1o10 11z0 1o10 11z0 1o10 11z0 1qN0 11z0 1o10 11z0 1o10 11z0 1o10 11z0 1o10 11z0 1qN0 WL0 1qN0 11z0 1o10 11z0 1o10 11z0 1o10 11z0 1o10 11z0 1qN0 WL0 1qN0 11z0 1o10 11z0 RB0 8x40 iv0 1o10 11z0 1o10 11z0 1o10 11z0 1o10 11z0 1qN0 WL0 1qN0 11z0 1o10 11z0 1o10 11z0 1o10 11z0 1o10 1fz0 1cN0 1cL0 1cN0 1cL0 1cN0 1cL0 1cN0 1cL0 1cN0 1fz0 1cN0 1cL0 1cN0 1cL0 1cN0 1cL0 1cN0 1cL0 1cN0 1fz0 1a10 1fz0 1cN0 1cL0 1cN0 1cL0 1cN0 1cL0 1cN0 1cL0 1cN0 1fz0 1cN0 1cL0 1cN0 1cL0 s10 1Vz0 LB0 1BX0 1cN0 1fz0 1a10 1fz0 1cN0 1cL0 1cN0 1cL0 1cN0 1cL0 1cN0 1cL0 1cN0 1fz0 1a10 1fz0 1cN0 1cL0 1cN0 1cL0 1cN0 1cL0 14p0 1lb0 14p0 1nX0 11B0 1nX0 11B0 1nX0 14p0 1lb0 14p0 1lb0 14p0 1nX0 11B0 1nX0 11B0 1nX0 14p0 1lb0 14p0 1lb0 14p0 1lb0 14p0 1nX0 11B0 1nX0 11B0 1nX0 14p0 1lb0 14p0 1lb0 14p0 1nX0 11B0 1nX0 11B0 1nX0 Rd0 1zb0 Op0 1zb0 Op0 1zb0 Rd0 1zb0 Op0 1zb0 Op0 1zb0 Op0 1zb0 Op0 1zb0 Op0 1zb0 Rd0 1zb0 Op0 1zb0 Op0 1zb0 Op0 1zb0 Op0 1zb0 Rd0 1zb0 Op0 1zb0 Op0 1zb0 Op0 1zb0 Op0 1zb0 Op0 1zb0 Rd0 1zb0 Op0 1zb0 Op0 1zb0 Op0 1zb0 Op0 1zb0 Rd0 1zb0 Op0 1zb0 Op0 1zb0 Op0 1zb0 Op0 1zb0 Op0 1zb0|21e6");

如果您想在区域之间convert，则必须添加目标和目标区域，例如：

＆＃13;

区域信息采用here所述的打包格式，而我从here获取区域值。

无论如何请注意，时刻时区提供moment-timezone-with-data-2010-2020.min.js，其中包含2010年至2020年的所有区域数据，仅为33 KB。

什么数据加载到时刻时区
