描述： RPC-499是指格林尼治标准时间08/03/06上午7:34到格林尼治时间09/03/06上午7:34之间的24小时时间段。
似乎没有关于此时间段的任何记录或记忆。如果有，则是在RPC-499期间发生的，大概率是管理局植入的人造记忆。在RPC-499期间记录的所有管理局文档都被发现已追溯归档。
不存在与管理局伪造文件有关的记录。
附录-1：目前为止，试图寻找RPC-499期间出现的任何物理证据都没有结果，除了三份文件。
RPC-499-A似乎是西纪念医院在08/03/06的一份出生记录拷贝。RPC-499-A, in addition to the other births of the day, 还将此婴儿记录为凌晨3:34（格林尼治标准时间7:34）出生。婴儿的姓名、性别和与其有关的任何附加信息都被涂黑。Attempts to contact Hospital staff have remained inconclusive, with any and all individuals showing no recollection of the "expunged" birth record. Current records do not include the expunged birth at all.
RPC-499-B is the original document for RPC-499. Discovered by a filing clerk in 2010, the document listed only the following sentence:
RPC-499 is the designation for the 24-hour time period between 7:34 AM GMT 08/03/06 and 7:34 AM GMT 09/03/06.
Attempts to link the original handwriting to the individual deemed responsible have thus far proven inconclusive.
RPC-499-C is the designation for an audio cassette, labeled "8-03-2006" in permanent marker. RPC-499-C is believed to originate from Memorial Hospital West. The fingerprints of a male and female were lifted from RPC-499-C, both deceased, from a car accident and childbirth respectively, 08/03/06. The contents of the cassette appear to have been wiped prior to acquisition.
Addendum-2: See RPC-876
