For the past year or so I have been getting Travel Warrants from work to
exchange for One-Day Travelcards (zones 1-6) for my travel into London
from the suburbs for work matters.

All worked well, until today, when I visited my local Southeastern
station and asked a staff member I hadn't seen before to do me a couple
of tickets, one for next week and one for the week after. He insisted
that he couldn't issue One-Day Travelcards more than a week in advance,
so I'd have to come back for the second one next week.

But was he right? Can all the staff at not just my local station but
also the other couple of stations I used on occasion to claim my tickets
have been wrong for all this time, and this one man right? And if he is
right, why do Southeastern's systems let them issue One-Day Travelcards
more than a *month* in advance? (I claimed 9 December on about
1 November.)

The rule in question has existed for a number of years (and, if memory
serves, was no more than *three* days in advance at one point).

The wording in "The Manual" is as follows:

-----Start of quoted text-----

*'In-Boundary' - within London Fares Zones 1-6*

The origin station on the ticket must be located within the Fare Zones
that the ticket is being issued for.

Tickets issued to start at a station within the Travelcard area must not
include travel to a station outside the Travelcard area.

Tickets are valid for travel from 0930 Monday to Friday on the date
shown on the ticket, and can only be issued at stations:-

+ on the day of travel – from 0930 Monday to Friday (excluding Public
Holidays), except where trains are timed to depart at or soon after 0930
when they may be issued before 0930. This will normally be after the
departure of the last restricted train, but where the train service
operator allows they may be sold before then.

+ in advance – from 0930 Monday to Friday, any time at weekends, and
Public Holidays, up to 7 days in advance of the day for which the ticket
is dated.

*'Out-Boundary'*

Where available Zones 1-6 Off-Peak Day Travelcards can be issued at
stations as follows:-

+ on the day of travel – after the departure of the last peak time
restricted train. Where Train Companies permit them to be issued
earlier, local instructions will be issued.

+ in advance – from 0930 Monday to Friday, any time at weekends, and
Public Holidays, up to 7 days in advance of the day for which the ticket
is dated.

-----End of quoted text-----

The restrictions on issue for Anytime (formerly Peak) Day Travelcards
are the same, but without the 0930 time restriction.
