Steps to reproduce:
Go to: Administration -> General -> GUI

Scenario 1:

1. Enter: Time filter default period = 10y
2. Submit

Scenario 2:

1. Enter: Time filter default period = 315359999s
2. Submit

Actual result:
Error message is displayed:

Cannot update configuration
Incorrect value for field "period_default": time filter default period exceeds the max period.

Expected result:
According to documentation 10 years (or 315360000 seconds) are in acceptable time range. For example, field 'Max period for time selector' has same allowed time period and it accepts 10y (or 315360000s) without issues.

If this time period is incorrect and 'Time filter default period' field should accept some other time period, then documentation needs to be corrected.
