How Can I Replace strptime() Functionality on Windows?

strptime() Alternative for Windows

strptime(), a function commonly used on POSIX systems to convert string representations of dates to tm structs, lacks an equivalent implementation on Windows. This article proposes a solution for implementing a similar functionality on Windows.

Implementation Using sscanf

To parse dates in Windows, a combination of the sscanf function and manual conversion to a tm struct can be utilized. Here's a step-by-step breakdown:

  1. Parse the date string using sscanf to extract the date components into integers.
  2. Copy the extracted integers into a tm struct, ensuring to decrement the month by 1 (as months are 0-11 in tm structs) and subtracting 1900 from the year (since years are represented as years since 1900 in tm structs).
  3. Utilize mktime to convert the tm struct into a UTC epoch integer.

Additional Considerations

When manually converting to a tm struct, remember to set the isdst member of the struct to -1. This will prevent any daylight savings-related issues.
