Hello:

I'm trying to figure out how to convert a floating point value into an 
interval of time. I'm calculating the time required to drive from point A to 
point B. For the sake of this question, we'll just say it is miles/speed. So:

drv_time = 478 / 45.0;

The value of this is: 10.6222222222222222

Is there a way of converting this value to an interval. It seems that INTERVAL 
only works with a quoted literal value.

If I type:
rnd=# select interval '10.8444444444444444 hours';         interval
----------------------------@ 10 hours 50 mins 40 secs
(1 row)

Anybody have an pointers?

Thanks...
