Timer mismatch

[Vixuzen]

The timer used in-game and the time recorded are sometimes mismatched.
e.g. 0:02 sometimes saves as 0:02 and other times as 0:03.
This is especially apparent when you read the text on the bottom.
e.g. The par time for the level is 0:02. You finish in 0:02 but the game might read it as 0:03, thus the game doesn't tell you about beating the par time and in level select it saves as 0:03.
Is it a rounding issue? I noticed it seems to happen mostly in the latter halves of the seconds (Above 0.5 it rounds up and below it rounds down)
