Wrong date in list report when traveling between timezones

[alex3kov]

To report a bug...

• What command(s) did you run?
  task 1 modify scheduled:2018-06-08
env TZ='Europe/London' task list
env TZ='Europe/Moscow' task list

• What did you expect to happen? Display the same date in "Due" column no matter the timezone.

• What actually happened? Different dates depending on TZ:

  
  $ env TZ='Europe/Moscow' task list
  ID Age Due        Description                      Urg 
  1 6w  2018-06-08 buy bilk                         7.03

$ env TZ='Europe/London' task list ID Age Due Description Urg 1 6w 2018-06-07 buy bilk 7.03

* Paste the output of the ```task diag``` command.

2018-06-08 is a valid ISO8601 date, but TW always adds the time component. It sometimes messes up dates when traveling between timezones.

This is not necessarily a bug. Needs more info regarding when the command above was run. It matters. There are times of day when the date is different in Moscow versus London.

Needs more info regarding when the command above was run.

I'm only entering the date in taskwarrior: task 1 modify scheduled:2018-06-08, without time, so I expect it to stay the same regardless of timezone. Taskwarrior adds the time component when no one asks it to (in json file).
