Re: Calculating relative time/distance from CURRENT_TIMESTAMP

Hi Amitabh,

Yes, I already took a glance of the Date/Time functions. But what I'm
expecting is something more meaningful/user-friendly value to be returned
than from the actual return value of these functions available here. I'm
just finding out whether this could be solved at query level itself.

For example, there is age(timestamp, timestamp) function. If I call like
this select age(current_timestamp, (current_timestamp - interval '1 day'))
it returns

"1 day". But what I'm expecting to be returned from the function is
something more meaningful/user-friendly to the end users. In this case, I
wanted it to return "yesterday", similarly today, 15 minutes ago, 1 week
ago, etc.

Regards,

Gnanam

Have you looked into the date time functions already ?

Hi,

Is there any built-in function/add-on module available in PostgreSQL, that
converts a given "timestamp"/"timestamptz" value into its relative distance
from CURRENT_TIMESTAMP? For example, relative distance as today, yesterday,
5 minutes ago, 1 week ago, etc.
