1 row in set, 2 warnings (0,02 sec)

mysql> ALTER TABLE pimitemtable ALTER atime SET DEFAULT 
current_timestamp();
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual 
that corresponds to your MySQL server version for the right syntax to use 
near 'current_timestamp()' at line 1

So based on the table schema, I tried

mysql> ALTER TABLE pimitemtable ALTER atime SET DEFAULT CURRENT_TIMESTAMP;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual 
that corresponds to your MySQL server version for the right syntax to use 
near 'CURRENT_TIMESTAMP' at line 1

So based on Server version: 5.7.24 Gentoo Linux mysql-5.7.24
https://dev.mysql.com/doc/refman/5.7/en/date-and-time-functions.html
I tried

mysql> ALTER TABLE pimitemtable ALTER atime SET DEFAULT NOW();
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual 
that corresponds to your MySQL server version for the right syntax to use 
near 'NOW()' at line 1

I'm having that anyway.
