![]() It then displays the TimeSpan object's properties. The following example instantiates a TimeSpan object that represents the difference between two dates.

The first method utilizes standard library functions like mktime(), providing a straightforward approach. In this blog, we have covered two methods to convert date and time to a timestamp in C. We then sum these values to obtain the final timestamp. In this method, we manually calculate the timestamp by considering the number of seconds in each year, month, day, hour, and minute since the Unix epoch (January 1, 1970). Timestamp += hour * MINUTES_IN_HOUR * SECONDS_IN_MINUTE Timestamp += (day - 1) * HOURS_IN_DAY * MINUTES_IN_HOUR * SECONDS_IN_MINUTE Timestamp += (month - 1) * DAYS_IN_YEAR * HOURS_IN_DAY * MINUTES_IN_HOUR * SECONDS_IN_MINUTE Long timestamp = (year - YEAR_OFFSET) * DAYS_IN_YEAR * HOURS_IN_DAY * MINUTES_IN_HOUR * SECONDS_IN_MINUTE Method 2: Using Custom Calculation #include Then, mktime() converts this struct tm to a time_t timestamp. ![]() The struct tm is initialized with the specific year, month, day, hour, minute, and second. In this method, we use the mktime() function from the header to convert a struct tm representing the desired date and time to a timestamp. Tm.tm_mday = 7 // Day of the month (1 - 31) Method 1: Using Standard Library Functions #include In this blog, we will explore various methods to achieve this task. In C programming, converting date and time to a timestamp requires careful handling to ensure accuracy and reliability. A timestamp, which represents a specific point in time, is often used for such purposes. In programming, managing dates and times is crucial, especially when dealing with databases, file systems, or network protocols. ![]()
