calculate epoch time in iPad

I have an array which contains time in HH:mm:ss format.

I want to convert this into epoch time. To convert a particular time into epoch, date along with time should be passed.

I want to pass today's date along with the time from array.

For example 09:15:30 (date 22/12/2011) which is a string, should be converted into 1324525530000 (corresponding epoch value)

How should I convert this ??

Any help is appreciated.

Maybe you can get an idea looking at this snippet:

NSDateFormatter * dateFormatter = [[NSDateFormatter alloc] initWithSafeDateFormat:@"dd/MM/yyyy HH:mm:ss"];
NSDate *date = [dateFormatter dateFromString:dateString];
NSTimeInterval epoch = [date timeIntervalSince1970];

Anyway you can have a look to NSDateFormatter and NSDate in the reference docs.

That looks like an epoch time in milliseconds - as far as I know it's supposed to be in seconds.

You can use NSDateFormatter to parse a string and convert it to a NSDate. This date can then return the seconds since 1970. If you really need it, simply multiply this by 1000.
