Very easy - you need to calculate the number of working days not including the first and last and multiply by the number of seconds between 07:00:00 and 22:45:00. Then, if the first day is a working day, add the number of seconds between the start of that day (or 07:00:00 if the timestamp is earlier) and 22:45:00. Then, if the last day is a working day, add the number of working seconds in it.
Turning a timestamp into a date, checking what day of the week this date falls on, and adding a day to the date are all simple tasks.
