New $dateToParts operator
Converts a date into its consituent parts.
A short cut for having to use a date extracting operator for each element:
db.cities.aggregate( [
{ $project: {
_id: 0,
blownUp: { *$dateToParts:* {
date: ISODate(),
timezone: "-04:30"
} }
} }
] );
{ "blownUp" : {
"year" : 2017, "month" : 7, "day" : 27,
"hour" : 11, "minute" : 3, "second" : 54, "millisecond" : 966
} }
db.cities.aggregate( [
{ $project: {
_id: 0,
blownUp: { *$dateToParts:* {
date: ISODate(),
timezone: "-04:30",
*iso8601: true,*
} }
} }
] );
{ "blownUp" : {
"isoYear" : 2017, "isoWeekYear" : 30, "isoDayOfWeek" : 4,
"hour" : 11, "minute" : 6, "second" : 44, "millisecond" : 502
} }
