Bad info: Max latency in ms - its in seconds

```
Hello
I found small problem in info log which can be confusing.

line 154 in wfs - version 2.04 (and 2.03 too)
log INFO "Max latency in ms: $MAX_LATENCY"

but correct is 
log INFO "Max latency in seconds: $MAX_LATENCY"

because paramter of ping -W is in seconds

Thanks for your work
