Time Range Controls
Throughout the Preseem application there is a common interface for selecting and filtering the time range that is used to visualize the data in the various charts and graphs.
This page describes supported time units and relative ranges, the common time controls, and the syntax that is used to customize the range used.
Time units and relative ranges
The following time units are supported: s (seconds), m (minutes), h (hours), d (days), w (weeks), M (months), and y (years).
The minus operator allows you to step back in time, relative to now. If you wish to display the full period of the unit (day, week, month, etc.) append /<time unit> to the end.
Here are some examples:
Relative Range  From Value:  To Value 
Last 5 minutes  now5m  now 
The day so far  now/d  now 
This week  now/w  now/w 
Previous Week  now1w/w  now1w/w 
Week to date  now/w  now 
Previous Month  now1M/M  now1M/M
