All graphs are one or two minutes behind. If I change to the Values view, then I have the latest values.

For example,

2019-12-23 11:35:02	
up (1)
2019-12-23 11:34:02	
up (1)
2019-12-23 11:33:02	
up (1)
2019-12-23 11:32:02	
up (1)
2019-12-23 11:31:02	
up (1)

but the 15 min graph only goes to 11:32 and the 3 hour graph only goes to 11:29
