Get just the hour of day from DateTime using either 12 or 24 hour format as defined by the current culture

阅读更多关于 Get just the hour of day from DateTime using either 12 or 24 hour format as defined by the current culture

.Net has the built in ToShortTimeString() function for DateTime that uses the CultureInfo.CurrentCulture.DateTimeFormat.ShortTimePattern format. It returns something like this for en-US: "5:00 pm". For a 24 hour culture such as de-DE it would return "17:00". What I want is a way to just return just the hour (So "5 pm" and "17" in the cases above) that works with every culture. What's the best/cleanest way to do this? Thanks! // displays "15" because my current culture is en-GB Console.WriteLine(DateTime.Now.ToHourString()); // displays "3 pm" Console.WriteLine(DateTime.Now.ToHourString(new

How to convert the integer date format into YYYYMMDD?

阅读更多关于 How to convert the integer date format into YYYYMMDD?

Python and Matlab quite often have integer date representations as follows: 733828.0 733829.0 733832.0 733833.0 733834.0 733835.0 733836.0 733839.0 733840.0 733841.0 these numbers correspond to some dates this year. Do you guys know which function can convert them back to YYYYMMDD format? thanks a million! The datetime.datetime class can help you here. The following works, if those values are treated as integer days (you don't specify what they are). >>> from datetime import datetime >>> dt = datetime.fromordinal(733828) >>> dt datetime.datetime(2010, 2, 25, 0, 0) >>> dt.strftime('%Y%m%d')
