Can someone suggest me how I can convert a variable that contain time in millisec to an exact date? The code is below:
long long SenderTimestamp=System::currentTimeMillis();
obviously the time in millisec is in the variable SenderTimestamp
Thanks

Did you try anything? – Thomas Ayoub Jan 08 '14 at 09:39

@Vladp I try to follow the code suggest in the link...but there are some fields that I can't understand like: boost::posix_time::ptime dt = boost::posix_time::from_time_t(tt); – CecchinoSMI Jan 08 '14 at 09:55

@Vladp I think that boost is the name of the struct, so I need to create a new struct to use this kind of format date? – CecchinoSMI Jan 08 '14 at 09:59

@Samoth Can you help me to understand how to adapt the solution described in the link above to my case? – CecchinoSMI Jan 08 '14 at 10:03

Why don't you just try that `std::time_t tt = static_cast
(ticksFromEpoch/1000)` ? – Thomas Ayoub Jan 08 '14 at 10:09 -
@Samoth Because nothing happens when I add just this line...the value of my variable is in milliseconds yet – CecchinoSMI Jan 08 '14 at 10:19

Give us a sample of desired output – Thomas Ayoub Jan 08 '14 at 10:27

@Samoth Ok...I have the variable
has a millisecond values, but I need to visualize it like a human format, for example 11:35:49:642 – CecchinoSMI Jan 08 '14 at 10:34

In your case this is simpler :
int seconds = (int) (milliseconds / 1000) % 60 ;
int minutes = (int) ((milliseconds / (1000*60)) % 60);
int hours = (int) ((milliseconds / (1000*60*60)) % 24);

Ok but...I need more clarity.... milliseconds means my variable? and how I can set these three values (seconds, minutes, hours) in a single variable? – CecchinoSMI Jan 08 '14 at 10:53

1+1, but I think it is better to use `static_cast
` instead, since the question is tagged `C++`, see: http://stackoverflow.com/questions/103512/in-c-why-use-static-castintx-instead-of-intx – Moha the almighty camel Jan 08 '14 at 10:55
