In addition to specify an absolute point in time (as explained above) you can also use points in time relative to now. Relative points in time can be specified in terms of years, months, days, hours and minutes as follows:

• @Yn addresses yearly data n years in the past. Example: When you are in 2016 and specifiy "[th0temp-max@Y1]" it will return the maximum outdoor temperature of last year (2015), while "@Y3" will address data from 2013.
• @Mn addresses monthly data n months in the past. Example: "[wind0wind-max@M0] will return max wind speed of current month, while "[wind0wind-max@M1]" will return max wind speed of previous month.
• @Dn addresses daily data n days in the past. Example: "[th0temp-min@D7]" will return minimum outdoor temperature of the current day, one week in the past.
• @hn addresses hourly data n hours in the past.
