Can't open and lock time zone table

Can't open and lock time zone table

Hi All

I found below warning log in events log folder:

"Can't open and lock time zone table: Table 'mysql.time_zone_leap_second' doesn't exist trying to live without them"

can everybody help me why this log is generated and how can I restore it?
FYI; ServiceDesk is working properly and no problem was senced. I am running on 6008 version.

Thanks
