Omg I deleted my admin account, not sure how I did it... but I need help please!

I have command line access I just cannot get into the admin site.

How do I restore the account from the command line? I see several options I just not sure which I choose.

I found this, if this is what I need, but I'm not sure what I put in the date field:

zxsuite backup doUndelete {account} {"dd/MM/yyyy HH:mm:ss"|first} {"dd/MM/yyyy HH:mm:ss"|last} [attr1 value1 [attr2 value2...]]

Is this the right procedure? How do I find the date of the restore I need?

Thanks a bunch!
