[ic] UserDB Last Login bug when running with mysql

[Carl Bailey]

Using IC 5.4, we noticed that the user's last login time in the UI was 
showing up as December 1969 for everyone.  We traced the issue to this:

The mysql column type is timestamp, which returns the data like 
YYYYMMDDHHMMSS.
However the UI page customer_view.html uses a [time] tag to display the 
value.  The problem is that the time tag only works correctly when 
given a "unix" time value, and fails when given the mysqlvalue above.

We solved it by changing the UI page as follows:
         [calc]
             my $dt = "[loop-param mod_time]";
             $dt =~ m/(\d{4})(\d{2})(\d{2})(\d{2})(\d{2})(\d{2})/;
             return "$2/$3/$1 $4:$5:$6"
         [/calc]

However, this fix works only for mysql and does not allow such flexible 
formatting as the time tag.
A more general fix would be to adjust the time tag something along the 
lines that follow:

-- use POSIX qw(ceil strftime LC_CTYPE);
++ use POSIX qw(ceil mktime strftime LC_CTYPE);

my $now = $opt->{time} || time;
++ if (length($now) == 14) {
++  # we have a mysql timestamp on our hands
++  $now = m/(\d{4})(\d{2})(\d{2})(\d{2})(\d{2})(\d{2})/;
++  my $now = mktime($6,$5,$4,$3,$2 - 1,$1 - 1900);
++}
