Review comment:
This is a bash feature, SECONDS is incremented under the hood:
```
SECONDS
Each time this parameter is referenced, the number of
seconds since shell invocation is returned. If a value is assigned to SECONDS,
the value returned upon subsequent
references is the number of seconds since the assignment plus
the value assigned. If SECONDS is unset, it loses its special properties, even
if it is subsequently reset.
```
(from man bash)
