Member Function Documentation

timeCodeToMinutes()

static uint16_t ace_time::ZoneInfoMid::timeCodeToMinutes ( uint8_t  code, uint8_t  modifier  )

inlinestatic

Convert (code, modifier) fields representing the UNTIL time in ZoneInfo or AT time in ZoneRule in one minute resolution.

The code parameter holds the AT or UNTIL time in minutes component in units of 15 minutes. The lower 4-bits of modifier holds the remainder minutes.

Definition at line 393 of file ZoneInfoMid.h.

toDeltaMinutes()

static int16_t ace_time::ZoneInfoMid::toDeltaMinutes ( uint8_t  deltaCode )

inlinestatic

Convert the deltaCode holding the RULES/DSTOFF field in ZoneEra or the SAVE field in ZoneRule to the delta offset in minutes.

The lower 4-bits stores minutes in units of 15-minutes, shifted by 1h, so can represent the interval [-01:00 to 02:45].

deltaMinutes = deltaCode * 15m - 1h

Definition at line 372 of file ZoneInfoMid.h.

toOffsetMinutes()

static int16_t ace_time::ZoneInfoMid::toOffsetMinutes ( uint8_t  offsetCode, uint8_t  deltaCode  )

inlinestatic

Convert the offsetCode and deltaCode holding the STDOFF field of the ZoneEra into minutes.

The offsetCode is rounded towards -infinity in 15-minute multiples. The upper 4-bits of deltaCode holds the (unsigned) remainder in one-minute increments.

Definition at line 382 of file ZoneInfoMid.h.

toSuffix()

static uint8_t ace_time::ZoneInfoMid::toSuffix ( uint8_t  modifier )

inlinestatic

Extract the 'w', 's' 'u' suffix from the 'modifier' field, so that they can be compared against kSuffixW, kSuffixS and kSuffixU.

Used for Zone.UNTIL and Rule.AT fields.
