    Make it easier.

    Don't work back 19 hours

    Work foward 5 hours

    because 24 - 19 = 5

    4:30 becomes 9:30

    Our hours are base 24, so -19 is the same as add 5

    4:30 -19 = 4:30 + 5 = 9:30

    Wow, I am getting slow in my days, took nearly 6 seconds to work this in my head.

    The time would have been 9:30 in the opposite meridian.

    14:30 in 24 hour format.

    24 hours ago = 4:30 am or pm

    19 hours ago = 9:30 am or pm

    19 hours before 4:30.

    Let's add 24 hours to 4:30, then subtract 19 from it:

    28:30 - 19:00 = 9:30

    30 minutes is one half of an hour. Let’s subtract these two numbers.

    t = 19 – 4.5 = 14.5 hours

    One day is 24 hours.

    24 – 14.5 = 9.5

    The time is 9:30 on the next day.

    9:30 (I think that is correct)
