Getting current time with milliseconds

The "time" function in <time.h> will return the number of seconds since the epoch (ie. 00:00:00 on January 1, 1970, Coordinated Universal Time). The type of "time_t" is generally typedefed as "long int" on POSIX compliant systems. Finally, if we recall that a millisecond is 1/1000 of a second we can easily calculate the number of milliseconds since the epoch.

hi all,

I want to take current time with milli seconds in C. Does it have any header file to include to produce time in milli seconds.

Please mail me if any of u know.

Thank you.

You may try the "gettimeofday" function. It reports the time down to microsecond level. The function is included via <sys/time.h>.

If you are using Windows rather than standard C you can call

GetSystemTimeAsFileTime(...)

with returns the current time as the number of 100-nanosecond intervals that have passed since January 1, 1601.

Hi Banfa,

Actually we want to count current time in milliseconds and then has to show such a way that hr/min/sec/msec.

Would u tell me the header files and functions in c required or else an example c program.

Thank you.

or if you want it split in to hours etc

1. #include "windows.h"
2.  
3. FILETIME now;

5. GetSystemTimeAsFileTime(&now);

hi Banfa,

Thanks for ur best reply. But it doesnot works in linux. I need header files which is included in linux. Would u help me pls....

Please refer to my previous post mentioning the gettimeofday() function. It will provide what you need.

This will give you the time in the format HH:MM:SS:mmm
