How to convert QTime 12 to 24 hr format and viceversa

Question

I have QTime with current time displayed in screen and the time format I have to change based on selection 12/24. So how I can change the time 12/24 format of QTime.

Answer 1

It depends on how you get date or time from QTime. For example:

QDateTime dateTime;
dateTime = dateTime.currentDateTime();
qDebug()<< dateTime.date().toString("dd.MM.yyyy");
qDebug()<< dateTime.time().toString("H:mm:ss");
qDebug()<< dateTime.time().toString("h:mm:ss ap");

Output:

"03.04.2018"
"15:38:14"
"3:38:14 pm"

@Anonymouse I didn't get your question. you can get hour, minute, second separatly like this:

qDebug()<< dateTime.time().toString("h");
qDebug()<< dateTime.time().toString("mm");
qDebug()<< dateTime.time().toString("ss");
qDebug()<< dateTime.time().toString("ap");
qDebug()<< dateTime.time().toString("h ap");
qDebug()<< dateTime.time().toString("H ap");

output:

"14"
"12"
"15"
"pm"
"2 pm"
"14 pm"
