That's why I'm thinking otherwise, but this is what I have so far that leans towards the "counting" cause:

ARTICLE XXI—Credited Major League Service

A. Definition

Those Player rights expressly set forth in the Basic Agreement for
which a Player’s eligibility is dependent upon credited Major League
service will be determined as follows:

(1) One full day of Major League service will be credited for
each day of the championship season a Player is on a Major League
Club’s Active List. A total of 172 days of Major League credited
service will constitute one full year of credited service. A Player
may not be credited with more than one year of credited service, 172
days, in one championship season. Major League service will be
computed commencing with the date of the first regularly scheduled
championship season game, through and including the date of the
last regularly scheduled championship season game. This rule shall
apply uniformly to all Players and all Clubs notwithstanding differences
in a particular Club’s schedule.

(2) For purposes of calculating credited service, a Player will be
considered to be on a Club’s Active List if:
(a) placed on a disciplinary suspension by a Club, the Vice
President, On-Field Operations or the Commissioner, or on the
Disabled List;
(b) called to active military duty for up to two years or if called
to emergency duty by the National Guard for a period of up to
thirty days.
