Delete the "Generated Time data" HANA Live HANA SPS07

Hi Team

as part of completing HANA system setup for HANA Live it is required to "generate the time data" which i did for all the Granularities i.e., YEAR,Month,week,Day,Hour and Seconds.

and i realized the it will take up too much space on DB, now i wanted to UNDO / delete / get rid of the data which i generated for Hours and Seconds Granularities,

is this something possible or what are the options i have.

thanks
