SSTOD(<N seconds>)
 Converts seconds to days.
 Returns <expN> number of days that equal <seconds>.

 Useful in applications that handle time by days.

 * Total seconds exceed one day
 m_seconds = 90000

 days_spent = INT( SSTOD(m_seconds) )
 time_spent = TIMESTR(m_seconds)

 * Total time is days_spent plus time_spent
 * days_spent contains 1
 * time_spent contains "01:00:00"

 * Total seconds do not exceed one day
 m_seconds = 80000

 days_spent = INT( SSTOD(m_seconds) )
 time_spent = TIMESTR(m_seconds)

 * Total time is days_spent plus time_spent
 * days_spent contains 0
 * time_spent contains "22:13:20"
