Slack Node oldest and latest parameter datetime picker for channel history does not work

[bbougon]

Describe the bug
When I wanna get a slack channel history with Oldest and / or Latest messages, I pick a date and time from the input datetime picker but the results are not within the range of the choosen date and time

To Reproduce
Steps to reproduce the behavior:

1. Go to a 'Slack Node' with channel history parameterized
2. Pick a date from the datetime picker for either Latest or Oldest messages
3. Execute the workflow

Expected behavior
I wanna retrieve the results corresponding to the date and time chosen

Environment (please complete the following information):

• Image Docker n8n:latest (i.e 0.144.0)

Additional context
The issue is here (and a few lines down for oldest). The date time picked through the datetime picker is sent as datetime string (i.e: 2021-10-18 23:00:00) to the slack API whereas it should be a timestamp based string (i.e 1634590800.000000). See the slack API doc)
