Detailed Description

Low-level real time clock functionality.

This file contains functions for interacting with the real time clock in the Dreamcast. Generally, you should prefer interacting with the higher level standard C functions, like time(), rather than these.

Function Documentation

time_t rtc_boot_time ( )

Get the time that the sytem was booted.

This function retrieves the RTC value from when KallistiOS was started. As with rtc_unix_secs(), this is a UNIX-style timestamp in local time.

The boot time as a UNIX-style timestamp.
time_t rtc_unix_secs ( )

Get the current date/time.

This function retrieves the current RTC value as a standard UNIX timestamp (with an epoch of January 1, 1970 00:00). This is assumed to be in the timezone of the user (as the RTC does not support timezones).

The current UNIX-style timestamp (local time).
