Out of bounds pandas timestamp

[sarahmish]

In the mimic dataset, the "datetimeevents" table anonymizes records by shifting the time period of events. See here for complete explanation. This causes an issue for pandas timestamp since the new timestamps exist in a time period that exceeds the upper bound limit of the package. The error accompanied by this issue is pandas._libs.tslibs.np_datetime.OutOfBoundsDatetime: Out of bounds nanosecond timestamp: 2275-12-21 16:00:00.
