format specifier "%j" is day of year.
When you reach the next year ( 366+ Days)
counting starts at 1 again.

an alternate would be

set tdiff 12345678
set sec_in_day [ expr 60 * 60 * 24 ]

set days [ expr $tdiff / $sec_in_day ]
set sec_remain [ expr $tdiff % $sec_in_day ]

if {$days} {
        set tdiffstr "$days Days "
}

append tdiffstr [ clock format $sec_remain -fmt "%T" -gmt 1 ]
