I think access time includes reads too, if its enabled. But its been so long since I've seen a system that had atimes enabled, I'm not 100% positive.
Unless you know for a fact atimes are enabled on your filesystem, they may not be meaningful. atimes are a lot of disk writes for something so rarely used, and often turned off. I usually see them disabled in Linux by default. (It's an option when mounting the filesystem - 'noatime'.)

quotaoff
QUOTAON(8) BSD System Manager's Manual QUOTAON(8)
NAME
quotaon, quotaoff -- turn filesystem quotas on and off
SYNOPSIS
quotaon [-g] [-u] [-v] filesystem ...
quotaon [-g] [-u] [-v] -a
quotaoff [-g] [-u] [-v] filesystem ...
quotaoff [-g] [-u] [-v] -a
DESCRIPTION
quotaon announces to the system that disk quotas should be enabled on one or more filesystems. quotaoff announces to the system that the
specified filesystems should have any disk quotas turned off. The filesystems specified must have entries in /etc/fstab and be mounted.
quotaon expects each filesystem to have quota files named quota.user and quota.group which are located at the root of the associated file
system. These defaults may be overridden in /etc/fstab. By default both user and group quotas are enabled.
Available options:
-a If the -a flag is supplied in place of any filesystem names, quotaon/quotaoff will enable/disable all the filesystems indicated in
/etc/fstab to be read-write with disk quotas. By default only the types of quotas listed in /etc/fstab are enabled.
-g Only group quotas listed in /etc/fstab should be enabled/disabled.
-u Only user quotas listed in /etc/fstab should be enabled/disabled.
-v Causes quotaon and quotaoff to print a message for each filesystem where quotas are turned on or off.
Specifying both -g and -u is equivalent to the default.
FILES
quota.user at the filesystem root with user quotas
quota.group at the filesystem root with group quotas
/etc/fstab filesystem table
