You can view your EDCT if you have internet access:
EDCT LOOKUP
You can also look at the ATC System Command Center's Advisory Database:

I don't think the controller you talked to had the power or authority to punish you with a later EDCT -- but he might have taken some delight in the fact that your asking him to do a little work was followed by the announcement of a further delay to you.
