datevec datenum conversion problem

On my machine, using Matlab R2014a, datevec(datenum(x)) produces result different from x:

>> datevec(datenum([2007, 4, 1, 30, 0, 0]))

ans =

        2007           4           2           6           0           0

Is this a bug, or am I doing something wrong?

Faber, looks good to me. 30h = 24h + 6h, in other words, the date corresponds to April 2, 6:00 AM.
