Does pbs\_sched work correctly if holidays continue over 7 days?

When I was investigating another bug (see [Wrong holidays file makes scheduler infinite loop](http://community.openpbs.org/t/wrong-holidays-file-makes-scheduler-infinite-loop/1387)),  
I found the following code snippets in prime.c, at line 511.

```auto
static time_t
end_prime_status_rec(time_t start, time_t date,
    enum prime_time prime_status)
{
    struct tm *tmptr;
    enum days day;

    /* base case: if we're more then 7 days out the current prime status will
     * never end. We know this because the only prime settings are weekly.
     */
    if (date > start + (7 * 24 * 60 * 60))
        return (time_t) SCHD_INFINITY;

```

Then, I have question.  
If holidays continues over 7 days,  
is it work correctly?

For example, this year 2019, In Japan:

```auto
(..snip..)
   119 Apr 29 Showa Day (昭和の日)
   120 Apr 30 National holiday (*1) (国民の休日)
   121 May 1 Emperor Coronation (*2) (即位の日)
   122 May 2 National holiday (*1) (国民の休日)
   123 May 3 Constitution Memorial Day (憲法記念日)
   124 May 4 Greenery Day (みどりの日)
   125 May 5 Children's Day (こどもの日)
   126 May 6 Holiday falls on a sunday, it is observed on the monday after (振替休日)
(..snip..)

(*1) Under Japanese law, a weekday between two holidays becomes "National holiday".
(*2) This holiday is carried out specially only in 2019, by the replacement of the Emperor.

```

(Japanese in brackets is an official name of holiday, please ignore it. On the left side of bracket,  
I translated to English, but unofficially.)

In Japan, from 2019/04/26(Sat) to 2019/05/06 (mon),  
non-weekday (i.e., non-prime time) continues 10 days.  
And then, from 2019/05/07 (tue), it begins weekday (prime time) again.

Assuming that the head of holidays file as follows:

```auto
YEAR 2019
*
* Prime/Nonprime Table 
*
* Prime Non-Prime
* Day Start Start
*
  weekday 0600 1730
  saturday none all
  sunday none all
(...snip...)

```

If somebody write holidays setting like above,  
does scheduler work correctly, or we see some troubles?  
Excuse, I don’t have investigated above situation, so I don’t know what happens.

I sorry, but I don’t use holidays settings in our cluster, hence this is not important for us.  
However, perhaps other organization uses this configuration.

Thank you.
