Taking time from SIM900,not date,only time

Hi guys,can anyone help me with SIM900 as RTC,command for SIM900 to display time is: AT+CCLK? and it returns: +CCLK: "17/05/13,21:22:22+08" So,I would like my arduino to look only at 21:22,what is hours and minutes,not date and other things.How can this be done?

Sounds more like a programming question.

What do you suggest to do? Ask same question in other forum?

You can report your post and ask it to be moved.

For character arrays (not String with capital S), you can use strchr() as in the demonstration code below.

char reply[] = "+CCLK: \"17/05/13,21:22:22+08\"";
char *ptrTime;
// find comma
ptrTime = strchr(reply, ',');
if(ptrTime == NULL)
{
  // not found
}
else
{
  // increment pointer to point to time
  ptrTime++;
  // replace '+' by nul terminator
  ptrTime[8] = '\0':
  Serial.println(ptrTime);
}

Not compiled, not tested.
