On pitr restoring if specified wrong time (out of range provided by pbm list), there are at least to different errors may occure.

If error like:
Failed with "no chunk with the target time, the last chunk ends on {1682419209 3}"

We're getting restore info (pbm list --restore --out=json) like following:
*start : 1682421599
status : "error"
type : "pitr"
snapshot : "2023-04-25T10:35:05Z"
point-in-time : 1682420113
name : "2023-04-25T11:19:58.516638545Z"
error : "no chunk with the target time, the last chunk ends on {1682419209 3}"*

But if pbm produces error like following:
Failed with "no backup found before ts {1682418612 0}"

Restore info different:
*start : 1682421860
status : "error"
type : "snapshot"
name : "2023-04-25T11:24:20.285709967Z"
error : "no backup found before ts {1682418612 0}"*

There are different field set in responses and different restore types. That causes problems for us when we're parsing PBM response in PMM.
