rockbox/firmware/libc/gmtime.c, branch wolf3d My Rockbox tree Improve code for gmtime_r() 2017-02-03T19:40:55+00:00 Michael Sevakis jethead71@rockbox.org 2017-01-26T00:34:13+00:00 248bff5eb8c56dc3c8b4ff2e47c05c7c09cd4849 Unlike the current code, it does no looping to count days or do table lookups, which means running time doesn't increase with year or month. A good thing if it's call a lot, especially if the algorithm were asked to compute dates centuries or more from the epoch start. As a bonus, handles negative time values.

Move intrinsic RTC implmentation differences to driver files 2017-01-27T04:07:49+00:00 Michael Sevakis jethead71@rockbox.org 2017-01-26T00:32:15+00:00 58b849c451ac1281c14bfc535ab7f411a0b736e0 Some drivers set tm_wday just fine and do not need it coerced to be correct. Others set tm_yday, so don't overwrite what the driver sets; just zero it inside if it can't fill the field. Move calls to set_day_of_week() to the sorts of drivers that presumably required the hammer (FS#11814) in get_time() where the weekday isn't locked to the date.
