> The TTL per CF is in seconds, we will convert it to milliseconds when construct HStore.
And if it is HConstants.FOREVER, we will set it to Long.MAX_VALUE.
> {code:title=HStore.java}
>   public static long determineTTLFromFamily(final HColumnDescriptor family) {
>     // HCD.getTimeToLive returns ttl in seconds.  Convert to milliseconds.
>     long ttl = family.getTimeToLive();
>     if (ttl == HConstants.FOREVER) {
>       // Default is unlimited ttl.
>       ttl = Long.MAX_VALUE;
>     } else if (ttl == -1) {
>       ttl = Long.MAX_VALUE;
>     } else {
>       // Second -> ms adjust for user data
>       ttl *= 1000;
>     }
>     return ttl;

> {code}
