# bson_append_timestamp()

## Synopsis

    bool
    bson_append_timestamp (bson_t     *bson,
                           const char *key,
                           int         key_length,
                           uint32_t    timestamp,
                           uint32_t    increment);

## Parameters

bson | A bson_t.
key | An ASCII C string containing the name of the field.
key_length | The length of key in bytes, or -1 to determine the length with strlen().
timestamp | A uint32_t.
increment | A uint32_t.

## Description

This function is not similar in functionality to bson_append_date_time(). Timestamp elements are different in that they include only second precision and an increment field.

They are primarily used for intra-MongoDB server communication.

The bson_append_timestamp() function shall append a new element of type BSON_TYPE_TIMESTAMP.

## Returns

true if the operation was applied successfully, otherwise false and bson should be discarded.
