You don't state what part of the documentation you were reading, but I
strongly suspect you were reading about check_interval,
retry_interval, or notification interval.  Those are measured in
"intervals", the length of which is set by the interval_length
variable in the configuration.  The interval length is in seconds and
is set in the config file near where you quoted below.

Here you can set the interval length....

So, if you have interval_length = 60, then each interval is 60
seconds, if you set interval_length=5, then each interval is 5
seconds.  The default is to have a 1 minute (60 second) interval, so a
service with check_interval=5 will be checked every 5 minutes.

Illustrative Example: You want to run some checks every 15 seconds,
some every 40 and the rest every 5 minutes.  You need to set
interval_length=5 (global setting), then on the 15 second checks,
check_interval=3; on the 40 second ones, check_interval=8; and on the
rest, check_interval=60.

Note that those numbers were used due to 5 seconds being the lowest
common denominator.  I suspect that using the longest possible
interval will be more efficient for scheduling, and make no claims as
to what will happen if a new interval begins before all checks
executing in the prior interval are completed.

I hope I was a help.
