Old backups remove not working if the file name ends with 60 sec

[ghost]

When running this command: /usr/local/bin/zmbkpose -d 2d in order to delete backups older than 2 days, the command is not working if in the file name, we have 60 for seconds: example 201418081460.tar.gz because the data with 60 sec does not exist.

Could you please fix this issue? Thank you.
