|12h Shows time as h:mm am/pm, using 12-hour time. If this is missing, default shows time as H:mm, using 24-hour time.
|tz= Your local time zoneabbreviation. All time zones allowed by the template {{Time}} can be used. Please use the abbreviation shown there. This option incorporates summer time (daylight saving) changes in time zones that have them. So if you live in a place with summer time (daylight savings), it is better to use this option than the |offset= option.
|offset= Your local time zone difference compared to UTC in hours. This will not include summer time changes.
East of UTC: Use |offset=+n. For example, in China, use |offset=+8; in India, use |offset=+5.5.
West of UTC: Use |offset=-n. For example, in Arizona, use |offset=-7; in Venezuela, use |offset=-4.5.
Default is UTC.
If you include both |offset= and |tz= options, |offset= will be used and |tz= will be ignored.
