Atitit. Best Practice for converting Standard Time formats into seconds

 

For example, 00:01:19 is converted to 79 seconds, and is converted to each other.

 

One idea is to use div 60 mod... but it is troublesome...

 

A better way is to use stamp

...

 

Add a date to the foreground and use the timestamp for calculation...

Public static void main (String [] args) throws ParseException {

// TODO Auto-generated method stub

String s = "00:01:09 ";

Int sec = str2secs (s); // 69

System. out. println (sec );

Sec = 79; // 00:01:19

String date = "2014-01-01 ";

Date start = DateUtil. str2date_excpt (date + "00:00:00", true );

Long endTimestamp = sec * 1000 + start. getTime ();

Date end = new Date (endTimestamp );

String s = DateUtil. date2str (end, true );

String [] sa = s. split ("");

Return sa [1];

}

 

Private static int str2secs (String s) throws ParseException {

String date = "2014-01-01 ";

String full = date + "" + s;

Date dt = DateUtil. str2date_excpt (full, true );

Date dt2 = DateUtil. str2date_excpt (date + "00:00:00", true );

Int I = DateUtil. getSecondInterval (dt2, dt );

 

Return I;

}

How to convert the number of milliseconds to the standard timestamp in. net?

TimeSpan ts = new TimeSpan (1251790200000*10 );
Ts. Days indicates the number of Days.
Ts. Hours indicates the corresponding Hours,
Push classes in sequence.
Note:
// Parameters:
// Ticks:
// A time period expressed in 100-nanosecond units.
Public TimeSpan (long ticks );

You can also Add a variable of the DateTime type to get the time after addition and subtraction.

Converts Greenwich Mean Time to a common time format and inserts it into the database in the standard time format.

Is Greenwich Mean Time and time format a concept? How can they be converted? I also want to know.
