I hope someone can help me. I’m currently genertating a list of computer dates to see which need to be replaced (>3 years). Is it possible to echo this in a csv or excel? I made the following snippet: $env:COMPUTERNAME $ComputerSystem = Get-WmiObject -Class Win32_ComputerSystem $BIOS = Get-WmiObject -Class Win32_BIOS $BIOSageInYears = (New-TimeSpan -Start ($BIOS.ConvertToDateTime($BIOS.releasedate).ToShortDateString()) ..

I’m using Howard Hinnant’s time zone library. https://howardhinnant.github.io/date/tz.html My question: Is it possible to construct a date::local_time object from a std::chrono::time_point? What I want to to: // ‘tp’ exists and is some std::chrono::time_point object auto locTime = date::local_time<std::chrono::milliseconds>(tp); The constructor for this doesn’t exist so a get a compilation error. How do I do this ..

TLDR: std::chrono::sys_time<std::chrono::microseconds> tTimePoint; std::istringstream stream("2020-09-16 22:00:00.123456"); std::chrono::from_stream(stream, "%Y-%m-%d %H:%M:%S", tTimePoint); I expected the code above to parse the .123456 as microseconds. However, when running this tTimePoint only contains the date and time excluding subseconds. Longer: I am using Visual Studio 2019 with the cpplatest flag on Windows 10. I have a simple input where users ..

I cannot figure out how to echo the date and time, with a zero padded hour, to insert a timestamp in my batch files. The following is the set command that I use to echo the date and time: set _DateTime=%DATE:~10,4%-%DATE:~4,2%-%DATE:~7,2%_%time:~0,2%-%time:~3,2% echo _DateTime=%_DateTime% The following is what the code above generated in the console window ..

Given this code to get the timestamp from a date, std::time_t SecondsSinceEpoch(int year, int month, int day) { std::tm t{}; t.tm_year = year; t.tm_mon = month; t.tm_mday = day; t.tm_year -= 1900; –t.tm_mon; t.tm_isdst = -1; return std::mktime(&t); } it works perfectly for more recent dates, however upon testing 1970, 1, 1 it returns -1, ..

I`m using date library. I didn`t understand how to get difference between 2 time points in milliseconds? date::time_of_day<std::chrono::milliseconds> time1; date::time_of_day<std::chrono::milliseconds> time2; // set some time… auto diff = std::chrono::duration_cast<std::chrono::milliseconds>(time2 – time1); std::cout << diff.count() << " milliseconds" << std::endl; Error: no match for ‘operator-‘ (operand types are ‘date::time_of_day<std::chrono::duration<long long int, std::ratio<1, 1000> > >’ {aka ..
