Is There a Windows Alternative to strptime()?

Alternative to strptime() on Windows

Question:

Windows lacks the POSIX function strptime(), which translates date and time strings into tm structures. Is there an effective alternative for use on this platform?

Answer:

One practical solution that avoids code porting or relying on external libraries such as Boost involves the following steps:

1. Utilize sscanf to parse the date string.
2. Copy the resulting integers into a tm structure, adjusting for the zero-based month and 1900-based year in the tm structure.
3. Use mktime to obtain a UTC epoch integer.

Remember to set the isdst member of the tm structure to -1 to prevent daylight savings issues. This process offers a viable substitute for strptime() on Windows systems.
