Thread: problem with timeofday() function in cvs PostgreSQL

Hello

In this version I can't convert returned value to time. timeofday() return
text. I need convert to timestamp before. It is normal behavior? I
expected timestamp as returned type.

regards

It is documented to return a string for historical reasons:

You probably want now() instead of that function.

This is good reason. Thank you.

I can't use now() or others because I need actual time in transaction.

Thank you

Just cast the result of timeofday() to timestamp (with time zone, likely).
