Unveiling the "magic numbers" of time formatting in Go language.

And other programming languages (such as PHP'sY-m-d H:i:s) Different, Go language uses a fixed 'reference time' as a template when formatting date and time. This reference time is: 2006-01-02 15:04:05.

You might find this string of numbers strange, but each part represents the corresponding time element:

• 2006: Represents the year
• 01: Represents the month (January)
• 02: Represents the date (second day)
• 15Represents hours (24-hour format, 3 PM)
• 04Represents minutes
• 05Represents seconds

When you want to format time, just in the "format" stringSelect and combineThese "magic numbers" or their corresponding positions can be used to express the desired output style. For example, if you want to display the year, write it in the format string.2006If you want to display the month, just write it up01.

Flexiblely choose to display the date or time part

Understanding the reference time in Go language, now we can easily implement various time display requirements:

1. Show only the date (Year-Month-Day)

When you only need to display the specific date of content release to the user without going into the exact seconds, you can do this:

{# 假设 item.CreatedTime 是一个时间戳，例如 1609470335 #}
<div>发布日期：{{stampToDate(item.CreatedTime, "2006-01-02")}}</div>
{# 输出示例：发布日期：2021-01-01 #}

If you prefer the Chinese format, you can do it like this:

<div>发布日期：{{stampToDate(item.CreatedTime, "2006年01月02日")}}</div>
{# 输出示例：发布日期：2021年01月01日 #}

2. Only show time (hour:minute:second or hour:minute)

Sometimes, we may only be concerned with the time point of an event, such as the time of a comment, or the time an activity starts.

{# 仅显示时分秒 #}
<div>评论时间：{{stampToDate(comment.CreatedTime, "15:04:05")}}</div>
{# 输出示例：评论时间：10:45:30 #}

{# 仅显示时分 #}
<div>更新于：{{stampToDate(archive.UpdatedTime, "15:04")}}</div>
{# 输出示例：更新于：10:45 #}

3. Complete date and time format

This is the most common format, which includes dates and times:

<div>文章发布：{{stampToDate(item.CreatedTime, "2006-01-02 15:04:05")}}</div>
{# 输出示例：文章发布：2021-01-01 10:45:30 #}

4. Other customized date and time combinations

The flexibility of the Go language lies in the fact that you can use any character to connect these reference time elements, creating a format that matches your brand style or specific scenario.

• Month/Day format:

  
  <div>生日：{{stampToDate(user.Birthday, "01/02")}}</div>
  {# 输出示例：生日：05/20 #}
  

• The day of the week and date:

  
  <div>会议时间：{{stampToDate(event.Time, "Mon, 01-02")}}</div>
  {# 输出示例：会议时间：周五, 01-01 #}
  

• Date without leading zeros:

  
  <div>简短日期：{{stampToDate(item.CreatedTime, "2006-1-2")}}</div>
  {# 输出示例：简短日期：2021-1-1 #}
