Always leading hours in time field

I found that in the time column will indicate hours, though earlier such was not.

According to custom, decided to see how the function "insertTime". And I found it all strange. In fact, it should work right! But the result on the face. If the value of hours = 0, the condition if($tmp[0]) return true o_O

I corrected it is more precise condition if($tmp [0] != 0) - so began to work correctly. - Although it's strangemay be due because I have are using PHP 5.4 - and this condition works on another (Such opinion I have decided, because earlier I used PHP 5.2, and time displayed correctly).

Indeed. The reason is probably that $tmp[0] holds a string with '00' which is in fact not threated "false". would work as well and is probably more realiable.
