Use ruby's strftime()on dates/datetimes:
strftime()在日期/日期时间使用 ruby ：
<%= link_to timeslot.opening.strftime("%Y %m %d"), [@place, timeslot] %>
Have a look at the documentationto find out how the formatting works.
查看文档以了解格式的工作原理。

You should use a helper for this.
您应该为此使用助手。
If you want to convert from UTC to PST you can use the in_time_zonemethod
如果要从 UTC 转换为 PST，可以使用该in_time_zone方法
def convert_time(datetime)
time = Time.parse(datetime).in_time_zone("Pacific Time (US & Canada)")
time.strftime("%-d/%-m/%y: %H:%M %Z")
end
<%= link_to convert_time(timeslot.opening), [@place, timeslot] %>

to get the precise date formatting that you are looking for in your example use the following strftime format string "%-d/%-m/%y: %k:00 PST"
要获得您在示例中查找的精确日期格式，请使用以下 strftime 格式字符串 "%-d/%-m/%y: %k:00 PST"
However, that may not be exactly what you want.Please clarify in your question (a) what you want to do with the time field (e.g. are you always wanting to display a time on the hour? X:00) and (b) are you always wanting to report PST times or do you want to print the actual timezone, or do you want to convert to PST??
但是，这可能不是您想要的。请在您的问题 (a) 中澄清您想对时间字段做什么（例如，您是否总是想在整点显示时间？X:00）和 (b)您是一直想报告 PST 时间还是想打印实际时区，还是想转换为 PST？
