Convert Date to Timestamp in C++

#include <iostream> #include <ctime> #include <sstream> int main() { struct tm tm; std::string date_string = "2021-04-30 04:10:30"; std::istringstream ss(date_string); ss >> std::get_time(&tm, "%Y-%m-%d %H:%M:%S"); std::time_t timestamp = mktime(&tm); std::cout << timestamp << std::endl; return 0; }

Convert Date to Timestamp in C#

using System; class Program { static void Main() { string date_string = "2021-04-30 04:10:30"; DateTime dateTime = DateTime.ParseExact(date_string, "yyyy-MM-dd HH:mm:ss", null); double timestamp = (dateTime - new DateTime(1970, 1, 1)).TotalSeconds; Console.WriteLine((int)timestamp); } }

Convert Date to Timestamp in Swift

let formatter = DateFormatter() formatter.dateFormat = "yyyy-MM-dd HH:mm:ss" if let date = formatter.date(from: "2021-04-30 04:10:30") { let timestamp = Int(date.timeIntervalSince1970) print(timestamp) }
