is this proper sql?

hi one of the developers here at work say this should work
insert into detail (det_id,det_mas_id,det_date,det_amt) values
(0,0,now(),'0'), (1,1,now(),'1');

but when i try that in postgres like:
insert into detail (det_id,det_mas_id,det_date,det_amt) values
(0,0,datetime'now','0'), (1,1,datetime'now','1');

i get
ERROR: parser: parse error at or near ","

now i personally dont think this is real sql
anyone?
