Function Documentation

◆ code_time()

int code_time	(	int	hour,
		int	minute,
		int	second )

inline

Encode hour, minute, and second into a single integer.

Parameters

hour	Hour component (0-23).
minute	Minute component (0-59).
second	Second component (0-59).

Returns: Encoded integer representing the time as HHMMSS.

This function combines the hour, minute, and second into a single integer for compact representation. The format is HHMMSS, where HH is the hour, MM is the minute, and SS is the second.

◆ decode_time()

hour_minute_second decode_time ( int nutc )

inline

Decode an integer into hour, minute, and second components.
