In Order to get difference between two timestamps in postgresql by hours, minutes, seconds and milliseconds we will be using EPOCH time difference. Let’s see how to
- Get difference between two timestamp in postgresql by hours with an example.
- Get difference between two timestamp in postgresql by minutes with an example.
- Get difference between two timestamp in postgresql by seconds with an example.
- Get difference between two timestamp in postgresql by milliseconds with an example.
Table we use is student_detail2
Get difference between two timestamp in postgresql by hours with an example:
Difference between two timestamp in hours can be calculated using EPOCH function by dividing 3600 because EPOCH returns difference in seconds as shown below
select *,EXTRACT(EPOCH FROM (birthtime -fin_time ))/3600 as diff_time_hours from student_detail2;
So the resultant table will be
Get difference between two timestamp in postgresql by minutes with an example:
Difference between two timestamp in minutes can be calculated using EPOCH function by dividing 60 because EPOCH returns difference in seconds as shown below
select *,EXTRACT(EPOCH FROM (birthtime -fin_time ))/60 as diff_time_min from student_detail2;
So the resultant table will be
Get difference between two timestamp in postgresql by seconds with an example:
Difference between two timestamp in seconds can be calculated using EPOCH function. EPOCH returns difference in seconds as shown below
select *,EXTRACT(EPOCH FROM (birthtime -fin_time )) as diff_time_sec from student_detail2;
So the resultant table will be
Get difference between two timestamp in postgresql by milliseconds with an example:
Difference between two timestamp in milliseconds can be calculated using EPOCH function by dividing 1000 because EPOCH returns difference in seconds as shown below
select *,EXTRACT(EPOCH FROM (birthtime -fin_time ))*1000 as diff_time_millisec from student_detail2;
So the resultant table will be
