time parsing error if timespan more then today:(

Hello,

I have installed WG++ on Synology NAS.

Its works fine until i set 'timespan' bigger than 0.

If I set for ex. "3" and run 'run.sh' i have got the following error:

update requested for - 18 - out of - 18 - channels for 3 day(s)
( 1/18 ) PORT.HU -- chan. (xmltv_id=RTL Klub) -- mode Force
iiinnnnnnnnnnnnnnnnnnnnn
Unable to update channel RTL Klub
Generic syntax exception:

time parsing error : String was not recognized as a valid DateTime.
nextstartdatetime time scrubbed :
computer date/time format: 27/12/2018 13:01:34
Existing guide data restored!

Cant find any solution. Please help.

Miklos
