I managed to change the time in Lubuntu to 12-hour format. Doing that in this operating system is a feat, but every day something new is learned, and I learned this by looking for a solution to the problem I have of resetting my laptop through NTP. It turns out that changing the letter "R" uppercase to lowercase, the 12-hour format comes out. Right-clicking on the time, selecting edit configuration, there it is changed, and you can have the normal format of 12 hours, with seconds and everything.
