Chances are you know that typing "time [city name]" into Google will give you the local time there. Turns out Google's search can also handle conversions between different time zones by name.
For instance, typing "2pm AEDT to AEST" will tell you that Queensland is continuing to be a nuisance and not embracing daylight saving. This ability can be useful if you're trying to work out the local equivalent of a meeting time and have only been given the time zone name (such as "PDT") rather than a city location.
For reference, these are the relevant time zones in Australia -- the daylight times apply October-March:
AEST: Australian Eastern Standard Time (NSW, Victoria, Queensland, ACT, Tasmania) AEDT: Australian Eastern Daylight Time (all AEST states except Queensland) ACST: Australian Central Standard Time (South Australia, Northern Territory, Broken Hill) ACDT: Australian Central Daylight Time (South Australia, Broken Hill) AWST: Australia Western Standard Time (Western Australia)
