Ignoring timestamps

I am trying to write some code which ignores the timestamps of the strings and reads the rest of the strings of varying lengths e.g.

14/07/20 18:27:02:533 ... C: SPLT 0x00 MTE_DL_RBSFN_STAT 0X00000001 0X00000000 0X00000000 0X00000000 0X00000000 0X00000000 0X00000000 0X00000000 0X00000000 0X00000000 0X00000000 0X00000000 0X00000000 0X00000000
14/07/20 18:27:02:533 ... SLOF
14/07/20 18:27:02:537 ... C: SLOF 0x00
14/07/20 18:27:02:541 forg l1 SetPortMapping 0
14/07/20 18:27:02:550 C: FORG 0x00 Ok l SetPortMapping 0

I am trying to use sscanf function to ignore the stamps and read rest of the string. This will happen in a loop. So I can not use defined %s and %*s. I need an algorithm to ignore part of the string i.e timestamps and read the remaining string. Thanks

You've noted that the timestamps aren't of fixed length. However, if it's always the case that the format is date timestamp the...rest..., then you could get the line as a string, then use string.find (twice) to find the second spacebar, e.g.

std::string s;
while (getline(input, s)) {
   size_t loc = s.find(' ');
   loc = s.find(' ', loc + 1);
   s = s.substr(loc + 1);
}
