Hello,
I am writing an extension that creates a DateTime object where I have
the unix timestamp and a UTC offset in minutes.
```
timelib_set_timezone_from_offset(ret->time, gt.offset);
timelib_unixtime2local(ret->time, gt.time);
```
Unfortunately, even though I can pull in the headers with
`#include <ext/date/lib/timelib.h>`, it doesn't seem those symbols are defined
anywhere to link:
```
$ readelf -Ws /usr/lib64/php8.0/lib64/libphp.so | grep timelib # nothing
```
Are these functions meant to be public? Can I use the headers as a public API
reference, or do I need to look somewhere else to see what is exposed?
Thanks for your clarifications,
