When you are interested in timestamps of min/max values, you can make use of these selectors:

• hmintime: timestamp of minimum value of this hour
• hmaxtime: timestamp of maximum value of this hour
• dmintime: timestamp of minimum value of today
• dmaxtime: timestamp of maximum value of today
• ydmintime: timestamp of minimum value of yesterday
• ydmaxtime: timestamp of maximum value of yesterday
• mmintime: timestamp of minimum value of this month
• mmaxtime: timestamp of maximum value of this month
• ymintime: timestamp of minimum value of this year
• ymaxtime: timestamp of maximum value of this year
• amintime: timestamp of minimum value of all time
• amaxtime: timestamp of maximum value of all time
• starttime: timestamp of first recorded value
• nonzerotime: timestamp of last occurrence of a nonzero value

Timestamps are strings of format "YYYYMMDDhhmmss". Year "YYYY" is reported in 4 digits, all other values (month "MM", day "DD", hour "hh", minute "mm", second "ss") come with 2 digits, leading zeros are not suppressed.

• age: reports seconds elapsed since last reception of data for that particular sensor.
• hold: reports seconds elapsed since last reception of data for that particular sensor, but returns invalid value when age is beyond data hold period of 300 seconds. This allows to return invalid status instead large number of seconds for sensors having dropped off long time ago.
