Changed .csv format after upgr. 7.1.0.3 -> 7.6.0.1

[Even]

The format of the .csv output file-name is changed after upgrade.

7.6.0.1 : OpsCenter_All_Failed_Backups_19_03_2014_07_00_58_494_AM_61.csv
7.1.0.3 : OpsCenter_All_Failed_Backups_19_03_2014_07.csv

How can I change it back to the "7.1.0.3-format" ?
