Archive to SFTP remove date time from file name

[paulwilltownsend]

Setup Archive and Kron to have a complete log of switch configurations,  Kron works fine but for some reason with the command below 

archive
path sftp://<username>:<password>@<serverIP>//MD-P2-HUB-STK/$h
write-memory

Host name of the switch is MD-P1-HUB-STK

the file name that is saved is 'MD-P1-HUB-STK-Mar--8-15-17-15.815-1'  how do I stop the date/time being amended to the end, Can I stop the date/time from being amended

Kron is automatic run' then it need to add timestamp to filename to make filename unique each time kron run and file save.
