Regarding Table Entity in Azure table storage

Question

I am using Java language and created a class which extends from TableServiceEntity.

public class GameLogsByHandGameId extends TableServiceEntity{

    private final String TABLE_NAME = "GameLogsByHandGameId";

    public GameLogsByHandGameId(String handId, String gameId) {
        this.partitionKey = handId;
        this.rowKey = gameId;
    }

    @Override
    public String getPartitionKey() {
        return this.partitionKey;
    }

    @Override
    public String getRowKey() {
        return this.rowKey;
    }

    public long getTableId() {
        return tableId;
    }

    public void setTableId(long tableId) {
        this.tableId = tableId;
    }

    public int getUserId() {
        return userId;
    }

    public void setUserId(int userId) {
        this.userId = userId;
    }

    @Override
    public String getTableName() {
        return TABLE_NAME;
    }

Any azure table entity has three system properties, PartitionKey,RowKey and Timestamp.

MSDN Documentation(https://msdn.microsoft.com/en-us/library/azure/dd179338.aspx) says "The server manages the value of Timestamp, which cannot be modified"

I do not have TimeStamp property in my entity; I though server would anyways insert it in table for every entity.

Though When I see my entity on Table storage; I do not see TimeStamp column?

Do I need to enable it or something?

No, you don't have to enable this property. It is there by default. If you look at TableServiceEntity documentation at http://azure.github.io/azure-sdk-for-java/com/microsoft/azure/storage/table/TableServiceEntity.html. You will see this property. It is called timeStamp in Java SDK.

Timestamp attribute is set by Azure Table Service when an entity is either created or updated. It denotes the date/time value in UTC when the entity was created/last updated.

As to why this column in not visible, it could be possible that the tool you're using chooses not to display this property. Could you try using other tool?
