推荐答案

尝试使用格式字符串中的大写HH

Try capital HH in your format string

HH      display two-digit hours on 24-hour scale

Format string pattern

MMM     display three-letter month
ddd     display three-letter day of the WEEK
d       display day of the MONTH
HH      display two-digit hours on 24-hour scale
mm      display two-digit minutes
yyyy    display four-digit year

尝试以时分秒为单位的HH

try For HH in hour minute second
