Steps To Reproduce:

Hide

criar um registro na coleção useevents

db.getCollection('useevents').insert({

"registeredAt" : ISODate("2019-10-27T02:00:30.627Z")

})

executar um aggregate

db.getCollection('useevents').aggregate([{"$group":{"_id":{ "day":{"$dayOfMonth":{"date":"$registeredAt","timezone":"America/Sao_Paulo"}}},"count":{"$sum":1}}}])

resultado esperado

 "_id" : {

 "day" : 26

},

 "count" : 1.0

resultado obtido

 "_id" : {

 "day" : 27

},

 "count" : 1.0

se alterarmos o aggregate executando colocando o offset manualmente, o resultado esperado é alcançado

db.getCollection('useevents').aggregate([

 {"$group":{"_id":{

 "day":{"$dayOfMonth":{"date":"$registeredAt","timezone":"-03:00"}}},"count":{"$sum":1}}}])

Description

On windows platforms it looks like certain time zone specifications are not parsed properly and are just silently ignored without being loaded. At this point it looks like it would be any file which contains a CTRL-Z character, which includes at least "America/Sao_Paulo".
