Measured on a PS4 (firmware 10.71) with an OpenOrbis homebrew that loads a probe PRX calling libSceRtc; every output starts as a sentinel, so stores and their width are visible. - sceRtcSetTime_t takes the low 32 bits of its argument as unsigned seconds and returns 0 for every value: -1 is 2106-02-07 06:28:15, 2^32 + 1 is 1970-01-01 00:00:01 and -2^31 is 2038-01-19 03:14:08. sceRtcGetTime_t stays 64-bit (2106-02-07 06:28:16 is 2^32). - sceRtcGetTime_t before 1970 and sceRtcGetWin32FileTime before 1601 store 0 and return 0x80B50008. Field validation still comes first and leaves the output unchanged (1969-13-01 returns 0x80B50009). - sceRtcSetTick and sceRtcSetWin32FileTime have no upper limit: the tick after 9999-12-31 23:59:59.999999 is 10000-01-01 and the file time 2^64 - 1 is 60056-05-28 05:36:10.955161. sceRtcGetDayOfWeek accepts years past 9999 (10000-01-01 is 6). - sceRtcFormatRFC3339 returns 0x80B50008 when the zone-shifted tick is outside years 1 to 9999. sceRtcFormatRFC2822 returns 0x80B50003 when it is negative as a signed value and 0x80B50008 when it is past 9999. The PS5-measured cases of GuestRtc.cpp that the probe repeated (RFC 3339 and RFC 2822 parsing, named and military zones, DOS time, TickAdd) give the same results on the PS4. The three expectations changed here (SetTick past 9999, SetTime_t(-1), RFC 2822 at the limit with +1 minute) came from commits that cite no measurement. Not yet confirmed on PS5.
