Java time processing:

Addition/subtraction,

// Current time

Date curdate = new date ();

// The current time is 6 minutes ago

Date presixmin = new date (curdate. gettime ()-integer. valueof (codeconstants. sms_overtime) * 60*1000 );

 

The above method uses the timestamp. js can also be used.

 

Oracle time addition and subtraction:

Sysdate + 6 -- plus 6 days, 1 unit 1 indicates 1 day

Sysdate + 6*1/24 -- add 6 h, 1 unit 1 indicates 1 day

Sendtime + 6*1/24/60 -- the value of sendtime is 6 minutes. Unit 1 indicates 1 day.
