missing milliseconds in timestamp while querying with mongo.find.all

[annkochepasova]

When I switch from working with mongo cursors (mongo.find) to fetching data frames (mongo.find.all) I get a data frame with POSIXct timestamps and those timestamps don't have milliseconds.

E.x:


res = mongo.find.all(...)

tsval = as.numeric(res$timestamp[1])

print(tsval, digits=20) 
# prints 1429294389

cursor = mongo.find(...)

tsval = as.numeric(mongo.bson.value(mongo.cursor.value(cursor), 'timestamp'))

print(tsval, digits=20) 
# prints 1429294389.1229999

Expected behaviour: Should receive the same result with milliseconds in both cases - 1429294389.1229999
