Make a DB Tag and use this expression:

```auto
if(dateExtract(now(),"min")=0 && dateExtract(now(),"sec")<5,1,0)
```

Hope this helps!

Slightly OT, but a variation on a theme.

5-sec pulse every quarter hour:

```auto
(switch(dateExtract(now(),"min"),0,15,30,45,1,1,1,1,0)) && (dateExtract(now(),"sec")<5)
```
