Ho scritto un piccolo script bash che mi ha fatto inciampare in "Bug 2038 anno" . Prima non sapevo di questo problema e ho solo il coraggio di pubblicare l' --debug
output che ho ricevuto da date
quando la mia sceneggiatura ha cercato di calcolare questa data magica (03:14:07 UTC il 19 gennaio 2038).
date -d "20380119"
date: parsed number part: today/this/now
date: input timezone: +01:00 (set from system default)
date: warning: using midnight as starting time: 00:00:00
date: starting date/time: '(Y-M-D) 2038-01-19 00:00:00 TZ=+01:00'
date: '(Y-M-D) 2038-01-19 00:00:00 TZ=+01:00' = 2147468400 epoch-seconds
date: output timezone: +01:00 (set from system default)
date: final: 2147468400.000000000 (epoch-seconds)
date: final: (Y-M-D) 2038-01-18 23:00:00 (UTC0)
date: final: (Y-M-D) 2038-01-19 00:00:00 (output timezone TZ=+01:00)

date -d "20380120" --debug

date: possible reasons:

C'è un modo per date
calcolare GNU attraverso questa data?
