QByteArray Datetime convert

Damian7546

Hi,

I have :
QByteArray dateTime = "20230326082227"; it possible in some simple way convert to format:
"2023-03-26 08:22:27"

?

@Damian7546 See if this works for you:

QString dateTime = "20230326082227";

QDateTime date = QDateTime::fromString(dateTime,"yyyyMMddHHmmss");

dateTime = date.toString("yyyy-MM-dd HH:mm:ss"));

This this for more information:
QDateTime::fromString()

Just pick out the character sequences as you want them. The first is 4 characters (2023), the next is 2 characters (03), and so on. Use QString::mid() or QString::sliced() for this. Then join the extracted strings back up to your desired output format.

You could indeed do it this way, I just don't see the point of converting this from a string to a datetime only to put that back into a string. Personal opinion I guess.

@JonB Because the OP seems to be working with date and time stamps, so I figured they needed a general solution. And it would benefit future readers I hope.

Absolutely no harm saying so your way :) Preference only. Just make 100% sure the fromString()/toString() work the same way as each other with regard to local time vs universal time.
