`show vrrp` on show the following warning:
```
Argument "1526314929 (Mon May 14 18:22:09 2018)" isn't numeric in subtraction (-) at /opt/vyatta/share/perl5/Vyatta/VRRP/OPMode.pm line 158.
Argument "1526314929 (Mon May 14 18:22:09 2018)" isn't numeric in subtraction (-) at /opt/vyatta/share/perl5/Vyatta/VRRP/OPMode.pm line 158.
```
might be because the new keepalived versions adds a date to the timestamp of 'last-transition'
possible fix:
`my $seconds = $stop - substr($start, 0, index($start, ' '));` at line 158 in OPMode.pm
