DateTime SYSTEMTIME conversion

Question

I am fetching a DateTime from a file via IStorageItem::GetBasicPropertiesAsync, but then I need to convert it to a SYSTEMTIME. I am not finding any built in routines to do it, and all the examples I come across are using the more full featured .net version as all I have available in my DateTime variable is UniversalTime. Do I need to write my own function to convert to/from the two times?

Regards, Guy

Hi,

First, you should get the UniversalTime of DateTime structure
http://msdn.microsoft.com/en-us/library/windows/apps/windows.foundation.datetime

Then use ULARGE_INTEGER convert this int64 value to FILETIME
http://msdn.microsoft.com/en-us/library/windows/apps/ms724284.aspx

At last, use FileTimeToSystemTime function to get SYSTEMTIME.

Best regards,
Jesse
