Get the current time in C

Question

I want to get the current time of my system  For that I m using the following code in C   time t now  struct tm  mytime   localtime  amp now    if   strftime buffer  sizeof buffer    X   mytime          printf  time1      s   n   buffer       The problem is that this code is giving some random time  Also  the random time is different everytime  I want the current time of my system

If you just need the time without the date     time t rawtime    struct tm   timeinfo    time   amp rawtime      timeinfo   localtime   amp rawtime      printf   02d  02d  02d   timeinfo- gt tm hour  timeinfo- gt tm min       timeinfo- gt tm sec

Copy-pasted from here     localtime example     include  lt stdio h gt   include  lt time h gt   int main        time t rawtime    struct tm   timeinfo     time    amp rawtime      timeinfo   localtime    amp rawtime      printf    quot Current local time and date   s quot   asctime  timeinfo          return 0      just add void to the main   arguments list in order for this to work in C

guys i got a new way get system time  though its lengthy and is full of silly works but in this way you can get system time in integer format    include  lt stdio h gt   include  lt stdlib h gt   int main         FILE  fp      char hc1 hc2 mc1 mc2      int hi1 hi2 mi1 mi2 hour minute      system  echo  time   gt time txt        fp fopen  time txt   r        if fp  NULL         exit 1        hc1 fgetc fp       hc2 fgetc fp       fgetc fp       mc1 fgetc fp       mc2 fgetc fp       fclose fp       remove  time txt        hi1 hc1      hi2 hc2      mi1 mc1      mi2 mc2      hi1- 48      hi2- 48      mi1- 48      mi2- 48      hour hi1 10 hi2      minute mi1 10 mi2      printf  Current time is  d  d n  hour minute       return 0

To extend the answer from  mingos above  I wrote the below function to format my time to a specific format   dd mm yyyy hh mm ss        Store the formatted string of time in the output void format time char  output       time t rawtime      struct tm   timeinfo       time    amp rawtime        timeinfo   localtime    amp rawtime         sprintf output     d  d  d  d  d  d   timeinfo- gt tm mday  timeinfo- gt tm mon   1  timeinfo- gt tm year   1900  timeinfo- gt tm hour  timeinfo- gt tm min  timeinfo- gt tm sec       More information about struct tm can be found here

Initialize your now variable   time t now   time 0      Get the system time   The localtime function is used to convert the time value in the passed time t to a struct tm  it doesn t actually retrieve the system time

You can use this function to get current local time  if you want gmt then use the gmtime function instead of localtime  cheers time t my time  struct tm   timeinfo   time   amp my time   timeinfo   localtime   amp my time   CCLog  quot year- gt  d quot  timeinfo- gt tm year 1900   CCLog  quot month- gt  d quot  timeinfo- gt tm mon 1   CCLog  quot date- gt  d quot  timeinfo- gt tm mday   CCLog  quot hour- gt  d quot  timeinfo- gt tm hour   CCLog  quot minutes- gt  d quot  timeinfo- gt tm min   CCLog  quot seconds- gt  d quot  timeinfo- gt tm sec
