Hello,
 I have requirement for applying time-zone on incoming data on basis of source type and host location both. 
 I know that we can put the timezone TZ on basis of the source type as follow: 
 [source::mysource]
 TZ=US/Pacific
and also on basis of hostname as follow: 
 [host::DC1*]
 TZ=US/Pacific
However, is it possible to combine these two parameters and put together as below in props.conf:
[source::mysource]
 [host::USDC*]
 TZ=US/Pacific
 [host::AUSDC*]
 TZ=Australia/Sydney
so that data of same source type and different sources can get time-zone correctly.
Please advise.
No, this is not something you can do.
