Date format is blank on Windows 11

[roboticforest]

The variable timeStr seems to be empty under Windows 11 builds, causing the output to be in nanoseconds only, which completely breaks sorting the log file output.

I'm told that %F and %T were Linux specific extensions. Reverting back to %Y-%m-%d %H:%M:%S (or upgrading to C++20 and using std::format) should provide a cross-platform solution.

logger/logger.cpp

Lines 94 to 107 in 981bcd0

	// Format the time as human readable.
	// "%F %T" --> "%Y-%m-%d %H:%M:%S" --> "TZONE 2019-08-23 13:42:58\0" (26 chars)
	char timeStr[26] = {0};
	std::time_t curTimeSecondPrecision = curTimeNanosecondPrecision/1000000000; // Deliberate integer rounding.
	std::strftime(timeStr, sizeof(timeStr), "%Z %F %T", std::localtime(&curTimeSecondPrecision));
	// Finally, print the time stamp.
	_buffer << '['
	<< timeStr
	<< ':'
	<< std::setw(9) << std::right << std::setfill('0')
	<< (curTimeNanosecondPrecision - curTimeSecondPrecision*1000000000)
	<< ']';
	_buffer << ' ';

Reverting the format string to use %Y-%m-%d %H:%M:%S did not work. It did remove the compilation warnings, but the output is still blank.
