Universal way to parse QString with non-fixed date-time formats for QDateTime conversion

Qnut

Hi

I need to parse a QString and convert it to QDateTime. My Problem is that the string is in users locale format, e.g. "24-4-2021 16:17:18" or "4/24/2021 16:17:18" or "24.04.2021 16:17:18". Depending on users locale even text format is possible like "Apr 24, 2021 4:17:18 pm".

Microsofts MFC has a function COleDateTime::ParseDateTime() that was able to handle different formats. Is their something similar in Qt or does anybody know about an open source solution?

Hi,

Isn't QLocale::toDateTime what you are looking for ?

Qnut

Thanks for the answer.

I am afraid QLocale::toDateTime still depends of the current QLocale setting. e.g. a QLocale("de_DE") cannot parse "3:45:21 pm" as german time has no concept of am/pm.

May be I can check several locales and can cover the most frequent time presentations used by the customers. I'll take a look at it ...

@Qnut said in Universal way to parse QString with non-fixed date-time formats for QDateTime conversion:

COleDateTime::ParseDateTime

Checking the documentation of that method, it does not seem to be as universal as you describe it. It also uses the system locale by default.
