I am using time() in Linux system to get current epoch. most of the cases, it gives correct epoch. but 3/4 times in every hour, it gives the epoch which is ahead of the current time.

have a look at my function, 

sub fetch_time
{
  Other variables declarations ...
  my($cur_ts);  <-- variable in which I am going to receive the epoch
  Other variables declarations ...

  # get the current timestamp
  $cur_ts = time(); <-- fetching current epoch
  print "$cur_ts;\n";

  Other operations ...
}

Samples
sample 1:
  system epoch - 1234867548
  epoch printed - 1234871946

sample 2:
  system epoch - 1234868856
  epoch printed - 1234873254

sample 3:
  system epoch - 1234928039
  epoch printed - 1234932437

Note: All the time, the difference coming in the range 4000 and above.

What may be the cause for this problem?
