mongo.timestamp.create(time, increment)

Arguments

(integer) date/time value (milliseconds since UTC epoch).

This may also be a "POSIXct" or "POSIXlt" class object.

Examples

mongo <- mongo.create()
if (mongo.is.connected(mongo)) {
    buf <- mongo.bson.buffer.create()
    # special Null timestamp -- automatically filled in
    # if one of first two fields in a record
    ts <- mongo.timestamp.create(0,0)
    mongo.bson.buffer.append(buf, "InsertTime", ts)
    mongo.bson.buffer.append(buf, "name", "Joe")
    b <- mongo.bson.from.buffer(buf)
    mongo.insert(mongo, "test.people", b)

    # create using a POSIXlt
    ts <- mongo.timestamp.create(strptime("05-12-2012",
        "%m-%d-%Y"), increment=1)
