How Can I Convert HH:MM:SS Time to Total Seconds?

Convert Time in HH:MM:SS Format to Flat Seconds

Converting time in HH:MM:SS format to a single seconds count is a straightforward task that can be accomplished using various programming techniques. Here's an in-depth look at the different approaches:

Explode and Convert

One method involves breaking down the time into its individual components (hours, minutes, and seconds) using the explode() function. Once separated, these components can be converted into seconds using the *60 multiplier for minutes and 3600 multiplier for hours:

import dateutil.parser

def convert_time_to_seconds(time):
    parsed_time = dateutil.parser.parse(time)
    total_seconds = parsed_time.hour * 3600 + parsed_time.minute * 60 + parsed_time.second
    return total_seconds

Regular Expression Magic

Regular expressions can also be used to extract and convert time in HH:MM:SS format to seconds. The following PHP code snippet uses preg_replace() and sscanf() functions to accomplish this task:

$str_time = "23:12:95";
$str_time = preg_replace("/^([\d]{1,2})\:([\d]{2})$/", "00::", $str_time);
sscanf($str_time, "%d:%d:%d", $hours, $minutes, $seconds);
$time_seconds = $hours * 3600 + $minutes * 60 + $seconds;

Handle MM:SS Format

Additionally, it's important to cater for cases where the input time is in MM:SS format (without hours). In such cases, you can modify the sscanf() call to handle this format:

sscanf(str_time, "%d:%d", $minutes, $seconds);
$time_seconds = $minutes * 60 + $seconds;

Conclusion

By employing these diverse approaches, you can efficiently convert time from the HH:MM:SS format to a flat seconds count, providing flexibility and accuracy in your time-related calculations.
