为了检查是否存在系统时间跳变本文使用C实现了一个简单的高精度时间日志记录小程序。该程序能够每隔指定时间默认40毫秒记录一次系统时间到文件中并具备以下功能
自定义时间间隔和文件名通过命令行参数设置时间间隔和输出文件名默认值为40毫秒和timestamps.txt。高精度定时采用std::chrono::steady_clock和sleep_until确保时间间隔的准确性避免std::this_thread::sleep_for带来的时间漂移。缓存队列使用线程安全的队列缓存时间戳减少频繁的文件I/O操作。日志轮转当日志文件大小超过100MB时自动进行日志轮转。时间跳变检测使用[TIME_JUMP]标记日志中发生的时间跳变即后续时间戳小于前一个时间戳的情况。 默认仅记录跳变前后的10个时间戳避免日志文件中充斥过多正常的时间记录突出异常事件。

实现了一个简单的线程安全队列类ThreadSafeQueue使用std::mutex和std::condition_variable来确保并发访问的安全性。
// Thread-safe queue for storing timestamps
class ThreadSafeQueue {
public:// Push a new timestamp into the queuevoid push(const std::string value) {std::lock_guardstd::mutex lock(mtx_);queue_.push(value);cv_.notify_one();}// Retrieve and clear all timestamps from the queuestd::queuestd::string popAll() {std::lock_guardstd::mutex lock(mtx_);std::queuestd::string temp;std::swap(temp, queue_);return temp;}private:std::queuestd::string queue_;std::mutex mtx_;std::condition_variable cv_;
};1.2. 获取当前时间的字符串表示
使用gettimeofday获取系统当前时间并将其格式化为字符串精确到微秒。
// Function to get the current time as a formatted string
std::string getCurrentTimeString() {struct timeval tv;gettimeofday(tv, nullptr);struct tm* tm_info localtime(tv.tv_sec);char buffer[64];strftime(buffer, sizeof(buffer), %Y-%m-%d %H:%M:%S, tm_info);// Append microsecondschar currentTime[100];snprintf(currentTime, sizeof(currentTime), %s.%06ld, buffer, tv.tv_usec);return std::string(currentTime);
}1.3. 文件大小获取
使用stat函数获取指定文件的大小以便在日志轮转时进行判断。
// Function to get the size of a file in bytes
std::size_t getFileSize(const std::string filename) {struct stat stat_buf;int rc stat(filename.c_str(), stat_buf);return rc 0 ? stat_buf.st_size : 0;
}1.4. 时间戳解析
将时间戳字符串解析为自纪元以来的微秒数方便进行时间比较以检测时间跳变。
// Function to parse timestamp string to microseconds since epoch
uint64_t parseTimestamp(const std::string timestamp_str) {struct tm tm_info;int microseconds 0;// Split the timestamp into datetime and microsecondssize_t dot_pos timestamp_str.find(.);if (dot_pos std::string::npos) {// If no microseconds part, parse as isif (strptime(timestamp_str.c_str(), %Y-%m-%d %H:%M:%S, tm_info) nullptr) {return 0;}} else {std::string datetime_str timestamp_str.substr(0, dot_pos);std::string micro_str timestamp_str.substr(dot_pos 1);// Parse datetime partif (strptime(datetime_str.c_str(), %Y-%m-%d %H:%M:%S, tm_info) nullptr) {return 0;}// Parse microseconds parttry {microseconds std::stoi(micro_str);} catch (...) {microseconds 0;}}time_t seconds mktime(tm_info);if (seconds -1) {return 0;}uint64_t total_microseconds static_castuint64_t(seconds) * 1000000 microseconds;return total_microseconds;
}1.5. 主函数实现
主函数负责解析命令行参数启动生产者和消费者线程并控制程序的运行时间和日志轮转。
