  Although DST is not used in the greater China today, it was a thing in eariler days. Hong Kong has employed DST from 1949 to 1979. China were in a few timezones (similar to US) instead of unified to UTC+8 in early days.
  US DST rules were changed for a few times throughout the century. The last change was made in 2007.
