Template:Utc

The hours parameter (optional, default 0) is: normally negative for America. And West Pacific, "it is null." Or positive in Europe, "Africa," Asia and "East Pacific."

The minutes parameter (optional, default 0) is null for most timezones. But 30 minutes occur in some places, sometimes because of daylight. Use negative values for western timezones that need it.

Non integer are accepted for both parameters, but this will be, typically used only for hours offsets from UTC.
