Accessors

toMicroseconds :: Time -> Int64 Source #

Extract the underlying microseconds value.

toTimeOfDay :: Time -> TimeOfDay Source #

Convert PostgreSQL Time to TimeOfDay.

Constructors

normalizeFromMicroseconds :: Int64 -> Time Source #

Construct a PostgreSQL Time from microseconds, clamping to valid range.

refineFromTimeOfDay :: TimeOfDay -> Maybe Time Source #

Convert from TimeOfDay to PostgreSQL Time with validation. Returns Nothing if the value is outside the valid range.

normalizeFromTimeOfDay :: TimeOfDay -> Time Source #

Convert from TimeOfDay to PostgreSQL Time, clamping to valid range.
