如何使用 yyyyMMddHHmmss 格式格式化当前时间？

如何使用 yyyyMMddHHmmss 格式格式化当前时间？

用

fmt.Println(t.Format("20060102150405"))

由于 Go 使用以下常量来格式化日期，请参阅此处

const (    stdLongMonth      = "January"    stdMonth          = "Jan"    stdNumMonth       = "1"    stdZeroMonth      = "01"    stdLongWeekDay    = "Monday"    stdWeekDay        = "Mon"    stdDay = "2"    stdUnderDay       = "_2"    stdZeroDay        = "02"    stdHour= "15"    stdHour12         = "3"    stdZeroHour12     = "03"    stdMinute         = "4"    stdZeroMinute     = "04"    stdSecond         = "5"    stdZeroSecond     = "05"    stdLongYear       = "2006"    stdYear= "06"    stdPM  = "PM"    stdpm  = "pm"    stdTZ  = "MST"    stdISO8601TZ      = "Z0700"  // prints Z for UTC    stdISO8601ColonTZ = "Z07:00" // prints Z for UTC    stdNumTZ          = "-0700"  // always numeric    stdNumShortTZ     = "-07"    // always numeric    stdNumColonTZ     = "-07:00" // always numeric    stdFracSecond0    = ".0", ".00" // trailing zeros included    stdFracSecond9    = ".9", ".99" // trailing zeros omitted)
