void	tr_rtc_ms_to_calendar (uint64_t ms_since_2000, tr_hal_rtc_date_time *date)
	Convert ms‑since‑2000 to a calendar (Y/M/D h:m:s.ms).
uint64_t	tr_rtc_calendar_to_ms (const tr_hal_rtc_date_time *date)
	Convert a calendar (Y/M/D h:m:s.ms) to ms‑since‑2000.

Detailed Description

Convert between ms‑since‑2000 and calendar.

Function Documentation

tr_rtc_calendar_to_ms()

uint64_t tr_rtc_calendar_to_ms

(

const tr_hal_rtc_date_time *

date

)

Convert a calendar (Y/M/D h:m:s.ms) to ms‑since‑2000.

Parameters

[in]

date

Calendar value to convert.

Returns

Milliseconds since 2000‑01‑01. Returns 0 if date is outside the supported range (e.g., < 2000 or >= 2100), per hardware limits.

Example

tr_rtc_date_time_t now_cal;
tr_rtc_calendar_get(&now_cal);
uint64_t hw_ms = tr_rtc_calendar_to_ms(&now_cal);

tr_rtc_ms_to_calendar()

void tr_rtc_ms_to_calendar	(	uint64_t	ms_since_2000,
		tr_hal_rtc_date_time *	date )

Convert ms‑since‑2000 to a calendar (Y/M/D h:m:s.ms).

Parameters

[in]	ms_since_2000	Milliseconds since 2000‑01‑01 00:00:00.000.
[out]	date	Output calendar.

Saturates at the supported calendar span (e.g., 2000..2099) if the input exceeds the hardware range. Millisecond resolution is preserved.
