Example
3 Symbols are used to indicate the time zones: SummerStandard or Winterand No dst.
The current time zone is shown on the right side of the locality.
Daylight Saving Time or summer time-except Lord Howe Island- it is 1h. more with respect to the standard o local time zone.
Winter Time or Standard local time UTC/ GMTis the one used the rest of the yearwhen there is no DST summer time.
Do not use daylight saving time throughout the year. (No Daylight Saving Time). The whole year uses the same time zone.
The hours +1h. +2h. etc. o -1h. -2h. etc. which appear to the right side of to the Locality inticate the Current Time Zone of the Locality just at the time of consultation.
For exampleif the symbol appears on the clock and you want to know the local time zonethe (UTC/GMT)you must subtract one hour (except Lord Howe 30 minutes)
it corresponds just with the standard time zone of the locality UTC/GMTor the winter time.
The time with the symbol as well as the winter symbolcorresponds to the local time or standard UTC/GMT time zonewith the difference that the time zone does not change throughout the year.
