date time (System.now()) value minus numeric field doesnt work

i have a trigger that will update a custom date/time field in my case but it seems like not working

This is my trigger:

c.SLA_Cont_Time__c = System.now() - c.SLA_Days_mins__c;

c.SLA_Cont_Time__c is my custom date/time field and c.SLA_Days_mins__c is a numeric field that i need to minus it to get latest value. but my c.SLA_Cont_Time__c keep getting the System.now() value instead. why it will not take the after subtraction value?

anything wrong?

Hi,

for minus the no of days use adddays() method.

 

try the below code snippet as reference :
datetime d1=system.now().adddays(-4);
system.debug('aa'+d1);

Thanks
