When grandfather Francis Sherlow received a hospital appointment through the post, he thought it should have come with a time machine.
To his astonishment, the letter asked him to attend an appointment on Thursday December 31.
But in the year 1840 and at midnight.
Mr Sherlow, 88, who lives in Leyland, said: “I couldn’t believe my eyes when I saw it.
“I may be old, but I wasn’t even born until 1923!
“It is just a silly letter that doesn’t make any sense.”
Mr Sherlow, who has two daughters and three grandchildren, has had two heart attacks in the past.
He also suffers from angina and is in a wheelchair.
And he has had prostate cancer for which he has injections.
One of Mr Sherlow’s daughters called Lancashire Teaching Hospitals to get to the bottom of the issue.
But embarrassed staff could find no record of the appointment.
Vikki Lewis, head of performance, capacity and business at Lancashire Teaching Hospitals, said: “Unfortunately, due to a human error, a letter has been issued to a patient that includes incorrect details about an appointment time.
“As a result of this mistake we have reviewed our processes and updated our system to ensure such errors will not occur in the future.
“We would like to apologise to the patient involved for any confusion or inconvenience caused.”
