bug: time format bug when timestamp is over 100 hours

[n4ru]

Hello,
there is a formatting bug when displaying timestamps of the current frame that are over 100 hours.
eg the timestamp has following value: 123 hours, 45 minutes, 67 seconds, 880 milliseconds
expected: 123:45:67.880
but shows: 12:3 :45.678
the full time is displayed correctly (see screenshot below or attachment).

i tested this with version 2.6.10 and 2.6.18 on windows, same error.

regards,
n4ru
