There are several several ways we can control the file timestamp on unix systems, touch command is useful to modify file to specific timestamp for:
1. access time
2. modified time
usage: touch option filename(s)
options:
-a = modify only access time
-m = modify only modified time
-r = reference copy the timestamp from file1 to file2
-d = add specifc timestamp to file
-t = add specific timestamp same as -d option but with different format

In general one unix node can access another node, this can be configured using a common unix account on all the nodes with same username, password could be different on each machine, for security we prefer to keep access at user level on each node. Generally we provide sudo access for this user to higher level access on machines.
