c++获取10位数时间戳的int和string格式

[墨香年少 32]

#include <iostream>
#include <chrono>
#include <string>

// 获取当前的时间戳（秒级）
int getTimestamp() {
    auto now = std::chrono::system_clock::now();
    auto duration = now.time_since_epoch();
    auto seconds = std::chrono::duration_cast<std::chrono::seconds>(duration).count();
    return static_cast<int>(seconds);
}

// 获取当前的时间戳（秒级）并转换为字符串
std::string getTimestampString() {
    auto now = std::chrono::system_clock::now();
    auto duration = now.time_since_epoch();
    auto seconds = std::chrono::duration_cast<std::chrono::seconds>(duration).count();
    return std::to_string(seconds);
}

int main() {
    int timestampInt = getTimestamp();
    std::string timestampStr = getTimestampString();

    std::cout << "Timestamp as int: " << timestampInt << std::endl;
    std::cout << "Timestamp as string: " << timestampStr << std::endl;

    return 0;

获取13位时间戳

#include <iostream>
#include <chrono>
#include <string>

// 获取当前的时间戳（毫秒级）
long long getTimestamp() {
    auto now = std::chrono::system_clock::now();
    auto duration = now.time_since_epoch();
    auto milliseconds = std::chrono::duration_cast<std::chrono::milliseconds>(duration).count();
    return milliseconds;
}

// 获取当前的时间戳（毫秒级）并转换为字符串
std::string getTimestampString() {
    auto now = std::chrono::system_clock::now();
    auto duration = now.time_since_epoch();
    auto milliseconds = std::chrono::duration_cast<std::chrono::milliseconds>(duration).count();
    return std::to_string(milliseconds);
}

int main() {
    long long timestamp = getTimestamp();
    std::string timestampStr = getTimestampString();

    std::cout << "Timestamp as long long: " << timestamp << std::endl;
    std::cout << "Timestamp as string: " << timestampStr << std::endl;

    return 0;
}
