Enterprise Monitor 4.5.2, ent_activation table having reserv

Server: Enterprise Server 5.0.1
Enterprise TOOL 4.5.2_jp

I am using Integration Monitor connecting to MS SQL Server 2000. I created tables from file “ent_logtable_mssql_create.sql” available in …\etc\adapter\logger45 directory.
I have done all the setup for proper logging.

When i connected IM to database after some transactions, I am getting 00:00:00 in the “Time” column.

After checking in the database i found that in the tables ent_activation & ent_message_log, the column “timestamp” is created as “[timestamp]”.
And may be because of that IM is not able to fetch timestamp column from the database.

Any tips are welcome
