I was lucky find the solution myself:
1) Close PI System Explorer
2) Restart System Explorer
3) The first element in your - last selected - model is selected. So no specific attribute is selected.
4) Go to 'View' > 'Trend', an empty trend will be shown - so no attribute is shown - and this allows you to reset your end date - in my case 2099 - back to a normal one :-)
Have a nice day...

Yes, the trends keep remembering the last used time periods.
I normally just open a trend / time series data dialog for a static value (no time series), and then change the time range to *-8h or something, before I try reopening the attribute I want. Usually does the trick!
Which version of PI System Explorer are you running? I just tried in PI System Explorer 2018 and I can't reproduce your issue:
(notice the 2099 timestamp at the bottom right).
Where you trending 1 attribute that has a PI Point data reference? Or were you trending an attribute with a different type of data reference?
