There are 2 bugs in the Air Date/Time Picker plugin found here: Air Date/Time Picker
Bug 1: AM/PM Not Displaying Correctly
The input always defaults to AM, even when the time is PM. For example, if the local time is 1:25 PM, the input’s placeholder and Initial Date will show 1:25 AM.
Bug 2:
The placeholder padding and text input padding are not the same. You can see in the picture below that the placeholder padding to the left is much more than the padding set when the text is visible. I have set the horizontal padding to be 10.
