Java code for getting current time

Question

I am searching code in java for fetching or synchronizing my local PC system time into my application

User · Answer

Both  new java util Date    and  System currentTimeMillis    will give you current system time

User · Answer

You can use new Date    and it ll give you current time   If you need to represent it in some format  and usually you need to do it  then use formatters   DateFormat df   DateFormat getDateTimeInstance  DateFormat MEDIUM  DateFormat MEDIUM  new Locale   en    EN     String formattedDate   df format  new Date

Try this   import java text SimpleDateFormat  import java util Calendar   public class currentTime        public static void main String   args            Calendar cal   Calendar getInstance            SimpleDateFormat sdf   new SimpleDateFormat  HH mm ss            System out println  sdf format cal getTime                  You can format SimpleDateFormat in the way you like  For any additional information you can look in java api   SimpleDateFormat  Calendar

Try this way  more efficient and compatible   SimpleDateFormat time formatter   new SimpleDateFormat  yyyy-MM-dd HH mm ss SSS    String current time str   time formatter format System currentTimeMillis       Log i  test    current time str     current time str

System currentTimeMillis    everything else works off that   eg new Date   calls System currentTimeMillis

To get system time use Calendar getInstance   getTime    And you should get the new instance of Calendar each time to have current time   To change system time from java code you can use a command line

new Date   getTime   is bugged       Date date   new Date        System out println date       System out println date getHours           date getMinutes           date getSeconds         long t1   date getTime        System out println  t1   1000   60   60    24          t1   1000   60    60          t1   1000    60       long t2   System currentTimeMillis        System out println  t2   1000   60   60    24          t2   1000   60    60          t2   1000    60     It returns me the wrong time millis  System currentTimeMillis   too  Since I ask the Date instance to tell me the corresponding time millis it must return the matching ones not others from a different time zone  Funny how deprecated methods are the only ones which return correct values

I understand this is quite an old question  But would like to clarify that   Date d   new Date      is depriciated in the current versions of Java  The recommended way is using a calendar object  For eg   Calendar cal   Calendar getInstance    Date currentTime   cal getTime      I hope this will help people who may refer this question in future  Thank you all

Just to inform for furthers developers  and thankfully to Basil Bourque  I just wanna add my stone to this topic   If you want simply get the HH MM SS format then do this   LocalTime hour   ZonedDateTime now   toLocalTime   truncatedTo ChronoUnit SECONDS     Cheers   P S   This will work only at least with Java 8

Not really sure about what you meant  but you probably just need  Date d   new Date

User · Answer

Like said above you can use   Date d   new Date      or use  Calendar getInstance      or if you want it in millis  System currentTimeMillis
