# Using Intervals To Offset Time
|
|
|
|
Postgres Intervals can be used with time as a way of determining a
|
|
standard offset. For instance, I can concisely determine what the time was 2
|
|
hours earlier with
|
|
|
|
```sql
|
|
> select now() - '2 hours'::interval as earlier;
|
|
earlier
|
|
-------------------------------
|
|
2015-06-12 21:17:43.678822-05
|
|
```
|
|
|
|
or similarly
|
|
|
|
```sql
|
|
> select now() - interval '2 hours' as earlier;
|
|
earlier
|
|
-------------------------------
|
|
2015-06-12 21:17:43.678822-05
|
|
```
