Technically, you are correct: There are two different time factors at play. The first is the validity of the Z-visa itself for entering China and the second is the duration of stay. On an X, Z, D, or J-1 visa, the duration of each stay is 000 day, in which "000" is regarded as 30 days, and that clock starts on the day of arrival irrespective of the date of issuance.
Legally speaking, you could arrive on the 89th day from the date the Z-visa was issued, travel around China for 28 days and then show up for work and apply for residency on the 29th day from the date of entry, but I was deliberating erring on the side of the angels, i.e., I wouldn't advise anyone to do it that way as a practical matter.
In regard to Z-visas, provinces apply different tolerances regarding when that legal duration of stay officially ends, which is why I advised Joel to notify the school of his intentions. A few will not make a fuss if the teacher applies for residency within the valid time frame of the Z-visa, while others will issue a fine for doing so if the duration of stay has exceeded 30 days from the day of entry.
To play it safe, i.e., to allow for unforeseen problems, one should arrive in China with at least 30 days of validity left on the Z-visa and then report to work well within 30 days from the day of arrival. Overstaying the duration of that single entry for more than 30 days (before having the Z-visa converted into a one-year residency permit) could be overlooked in the presence of a legal contract or it could lead to a fine, so anyone thinking about doing this should consult with the school first to determine the particular sensibilities of the local PSB.
Thank you for addressing the ambiguity in my reply to Joel. I have revised it in the interest of clarity.
As a general rule, it would not be a good idea to enter China on a Z-visa and then plan to travel with it for more than 30 days from the date of entry before reporting for work and applying for a residency permit.
