replace older time functions with more portable ones
As per https://www.gnu.org/software/libc/manual/html_node/Broken_002ddown-Time.html
@Gargaj I think your code is missing an important step:
Portability note: mktime is essentially universally available. timegm is rather rare. For the most portable conversion from a UTC broken-down time to a simple time, set the TZ environment variable to UTC, call mktime, then set TZ back.
This has been a while so I don't specifically remember what was being broken, but the functions I was trying to fix were not available on one of the current generation consoles.
I am encountering the same issue as @Gargaj, and the platform in question does not support time zone setting via functions like tzset().
I was able to workaround by defining replacements for timgm and other functions before including implot.cpp, but it is a bit of a hack. Perhaps for robustness of the ImPlot API, a #define could be optionally provided to override implementation of the time related functions, to enable implementation sites to control behavior for specific platforms.
@skarolewics Would you be able to share your replacement for timegm?
