   ### Feature Request / Improvement
   
   Hi folks,
   
   I would like to understand more about the statement "Avro type annotation 
adjust-to-utc is an Iceberg convention,” given that Avro already has the 
Logical Type local-timestamp-micros. Should Iceberg support both the 
`adjust-to-utc` and `local-timestamp-micros` methods simultaneously?
   
   timestamptz:
   
   https://iceberg.apache.org/spec/#avro
   
   ```
   {
     "type": "long",
     "logicalType": "timestamp-micros",
     "adjust-to-utc": true
   }
   ```
   
   and
   
   https://avro.apache.org/docs/1.10.2/spec.html#Decimal
   
   ```
   {
     "type": "long",
     "logicalType": "local-timestamp-micros"
   }
   ```
   
   Reference class:
   org.apache.iceberg.avro.SchemaToType#primitive
