BUG: `time_shift` associated with same `time_zone` argument change for different variables

Hello there,

I noticed what seems to be a bug when downloading daily data via the daily dataset. For some variables, when I put "time_zone": "utc+00:00", the API returns

Daily reduction: sum {'time_shift': {'hours': -1}, 'remove_partial_periods': True}

I’m getting it when downloading the tp variable. Here is my request:

{
    'product_type': ['reanalysis'], 
    'variable': ['total_precipitation'], 
    'year': ['2024'],
    'month': ['11'], 
    'day': ['25'], 
    'area': [90, -180, -90, 180], 
    'time_zone': 'utc+00:00', 
    'frequency': '1_hourly', 
    'daily_statistic': 'daily_sum'
}

However, when I request other variables – u10 for example, it does not shift by 1 hour:

Daily reduction: sum {'time_shift': {'hours':0}, 'remove_partial_periods': True}

I can workaround by making the time_zone utc+01:00 to actually get date unshifted, but it would be unsafe if this behavior is unexpected.
Thanks!

Does anyone has experienced the same issue?
