Detailed Description

Macro Definition Documentation

#define LTRX_EPOCH_YEAR 2000

The Lantronix epoch is year 2000; this is the base value for the elapsed seconds to the current time for functions ltrx_time_get(), ltrx_time_set(), ltrx_time_to_utc() and ltrx_time_from_utc().

uint32_t ltrx_time_from_utc ( struct ltrx_time * lt )

Broken-down time to seconds.

Converts the broken-down time lt into seconds since year 2000. Also writes back lt in normal form.

No timezone adjustments are made.

Parameters

[in,out] lt Structure with explicit calendar fields.

uint32_t ltrx_time_get ( void )

Get date and time.

Gets the number of seconds elapsed since the Lantronix epoch, January 1, 2000.

void ltrx_time_register_source ( const struct ltrx_time_source * lts )

Register a time source.

Registers a procedure into the system for setting and updating the time.

Registration must be done in early module initialization.

Parameters

[in] lts Designates the procedures to start and stop this service.

void ltrx_time_set ( uint32_t seconds_since_2000 )

Set date and time.

Sets the Real Time Clock (RTC) to number of seconds elapsed since the Lantronix epoch, January 1, 2000.

Parameters

[in] seconds_since_2000 Number of seconds since January 1, 2000.

Seconds to broken-down local time.

Converts the calendar time seconds_since_2000 to broken-down time representation, expressed relative to the user's specified timezone.

Parameters

[in]	seconds_since_2000	Number of seconds since January 1, 2000.
[out]	lt	Structure with explicit calendar fields.

Seconds to broken-down GMT time.

Converts the calendar time seconds_since_2000 to broken-down time representation, expressed in Coordinated Universal Time (UTC).

Parameters

[in]	seconds_since_2000	Number of seconds since January 1, 2000.
[out]	lt	Structure with explicit calendar fields.
