In case you’re restricted to legacy java.util.Date and java.util.Calendar APIs, you need to take into account that the timestamps are interpreted in milliseconds, not seconds. So you first need to multiply it by 1000 to get the timestamp in milliseconds. long seconds = 1320105600; long millis = seconds * 1000; This way you can feed … Read more
You can turn a date object into a long (milliseconds since Jan 1, 1970), and then use TimeUnit to get the number of seconds: long diffInMs = endDate.getTime() – startDate.getTime(); long diffInSec = TimeUnit.MILLISECONDS.toSeconds(diffInMs); Edit: -Corrected the name of the variable diffInMs which was written diffInM(i)s in the second line.
^(?:(?:([01]?\d|2[0-3]):)?([0-5]?\d):)?([0-5]?\d)$ Explanation: ^ # Start of string (?: # Try to match… (?: # Try to match… ([01]?\d|2[0-3]): # HH: )? # (optionally). ([0-5]?\d): # MM: (required) )? # (entire group optional, so either HH:MM:, MM: or nothing) ([0-5]?\d) # SS (required) $ # End of string
Try this: Calendar calendar = Calendar.getInstance(); calendar.setTime(yourdate); int hours = calendar.get(Calendar.HOUR_OF_DAY); int minutes = calendar.get(Calendar.MINUTE); int seconds = calendar.get(Calendar.SECOND); Edit: hours, minutes, seconds above will be the hours, minutes and seconds after converting yourdate to System Timezone!
function millisToMinutesAndSeconds(millis) { var minutes = Math.floor(millis / 60000); var seconds = ((millis % 60000) / 1000).toFixed(0); return minutes + “:” + (seconds < 10 ? ‘0’ : ”) + seconds; } millisToMinutesAndSeconds(298999); // “4:59” millisToMinutesAndSeconds(60999); // “1:01” As User HelpingHand pointed in the comments the return statement should be: return ( seconds == 60 … Read more
Brief Description The answer from Brian Ramsay is more convenient if you only want to convert to minutes. If you want Cocoa API do it for you and convert your NSTimeInterval not only to minutes but also to days, months, week, etc,… I think this is a more generic approach Use NSCalendar method: (NSDateComponents *)components:(NSUInteger)unitFlags … Read more
You can also just delay some operation this way: setTimeout(function (){ // Something you want delayed. }, 5000); // How long you want the delay to be, measured in milliseconds.
