Functions : getFormattedTime, re

getFormattedTime(messyTime, ampmSwitch)

Returns either:

• a string in the format of h:mm A where h is hour, mm is 2 digit minute and 'A' is AM or PM.
• null if format cannot be determined from messyTime
• 'h:mm A' format allows easy entry in Date object. Example:

new Date('01/01/2017' + ' ' + ft.getFormattedTime(950)); 
// returns Date object set to `Jan 01 2017 09:50:00`

• string, required
• the value that is to be converted into a reliable formatted time
