if %TIME = 9.29 then %TIMEVAR = %TIME+.01 returns 9.3

When adding a minute to a time variable, the result drops any trailing zero, invalidating the resultant time variable.

OR, the timer doesn't respect 1 digit minute decimal value of time variable.  Which is odd, because it is fine with the 1 digit hour portion.

Workaround: add a minute to the time, split the time by "." then append 00 to the 2nd portion and and select the left most 2 char before finally putting it all back together.
