Hi,
I have a string containing a time in format: "yyyy-mm-dd:HH:MM:SS"
I have to decrease this time value by a 3-digit hour value or 3-digit day value.
What could be the best of doing it? Only way I can think of is:
1) convert the string's time into seconds
2) convert the specified value into seconds
3) subtract them
4) convert the result back to a string.
Is there a better/more efficient way of doing it???
Thanks,
- Ruchikar.

Why not get the time, store its values as integers or something so you can do the manipluation, then convert them to a string by using itoa or something for display?

Read up on the mktime function
You can say things like
tm.tm_day += 3;
Then use mktime to normalise the time back into the correct ranges.
Or you could create a struct and write functions to manipulate with it.
>yyyy-mm-dd:HH:MM:SS
Something like this perhaps.
Code:struct TimeStruct { int yyyy; int mm; int dd; int hh; int mm; int ss; };
