number of seconds since 1970

I was watching today.Python APIwhen, see TimeModule:The epoch is the point where the time starts. On January 1st of this year, at 0 hours,the "time since the epoch" is zero. For Unix, the epoch is 1970. To the "What's The epoch is", look at Gmtime (0

Mktime(Converts the time structure data to the following number of seconds)Header file# Include Define functionsTime_tMktime(Strcut TM * timeptr );Function DescriptionMktime() Is used to convert the TM structure data referred to by the timeptr

Java.sql.date,java.sql.time and Java.sql.Timestamp Three are subclasses of Java.util.Date (wrapper class). Java.sql.Date is a subclass of Java.util.Date, a thin wrapper that wraps a millisecond value, allowing JDBC to identify the millisecond value

VC ++ obtains the system time and program running time (precise to seconds and milliseconds ). 1. Use the CTime class (get the current system time, accurate to seconds)CString str; // obtain the system time CTime tm; tm = CTime: GetCurrentTime (); //

(Only personal, if there is a difference, or not high efficiency also please point out, thank you)Recently in writing a back word app, according to Ebbinghaus curve to review the enhanced memory, need to calculate two review of the difference of

The time module provides a variety of functions and ways to identify the timing value, there are two main formats for identifying time: one is identified as a timestamp, which is the number of seconds from January 1, 1970 0:0, 0 seconds to the
