We have one application , we are downloading reports as excel, for the date we are converting from UTC to AEST while downloading from database , beacuse here automatic conversion will not happen.

previously we are doing Created date(Database UTC datae time)+ 10 hours

but we want some logic it can take care of AEDT( Daylight saving time)

so we created below logic using timezone extension but , it is working now for adding 10 hours , but after October first sunday will it  automatically convert from AEST to AEDT ?, or we need to do anything ?

currently we giventime zone identifier AEST.       AEDT when i try to given this one its saying its not valid time identifier.

will the "AUS Eastern Standard Time"= will give +11 output on October ? 

please check the below oml file
