Customizing Auto DST File
Before customizing, you need to obtain the AutoDST file. You can ask the distributor or Yealink FAE for DST tem-
plate. You can also obtain the DST template online: http://sup-
port.yealink.com/documentFront/forwardToDocumentFrontDisplayPage.
1.
Open the AutoDST file.
2.
To add a new time zone, add <DST szTime="" szZone="" iType="" szStart="" szEnd="" szOffset=""/ > between
<DSTData > and </DSTData > .
3.
Specify the DST attribute values within double quotes.
For example:
Add a new time zone (+6 Paradise) with daylight saving time 30 minutes:
<DST szTime="+6" szZone="Paradise" iType="1" szStart="3/5/7/2" szEnd="10/5/7/3" szOffset="30"/ >
Modify the DST settings for the existing time zone “+5 Pakistan(Islamabad)” and add DST settings for the exist-
ing time zone “+5:30 India(Calcutta)”.
4.
Save this file and place it to the provisioning server.
