Let’s add some parameter to set time format in RMAN. Add following parameter in your .bash_profile which resides in home directory of oracle user.


export NLS_LANG=american_america.al32utf8 
export NLS_DATE_FORMAT="yyyy-mm-dd:hh24:mi:ss"

Now , run .bash_profile file to give effect 

[oracle@prod-18c ~]$ . .bash_profile

Now , let us check backup using list backup command :

RMAN> list backup;

using target database control file instead of recovery catalog

RMAN>

Now , we can see in completion time column that time and date is printed in the given format of NLS parameters , we can compare it with output of list backup before setting nls parameters where there is only date printed in completion time column.
