code: func localTimeTooltip(innerText string, ifZero string, t time.Time) template.HTML {
  	return localTimeCommon(ifZero, t, "tooltip-only", innerText)
  }
docs: // localTimeTooltip is similar to localTime, but shows time in a tooltip and
  // allows to specify inner text to be added to the created <span> element.
  // Recommended usage: {{ .Date | localTimeTooltip "innerText" "N/A" }}
