The problem with this statement is that EPOCHREALTIME is permitted to get it wrong, yet EPOCHSECONDS is permitted to get it right. The discrepancy certainly came as a surprise to me. $ TZ=UTC faketime '1970-01-01' bash -c 'declare -p EPOCHSECONDS' declare -- EPOCHSECONDS="0" $ TZ=UTC faketime '1969-12-31' bash -c 'declare -p EPOCHSECONDS' declare -- EPOCHSECONDS="-86400" -- Kerin Millar
