Enable / Disable shipping module by DAY and TIME

[mc12345678]

Thanks for the reply - and the various cautions.

To keep it relatively simple, and not specify a time of day (in addition to the day concerned), the following configuration is acceptable - being the day of the week only:

MODULE ACTIVE: Monday, Tuesday, Wednesday, Thursday.
MODULE INACTIVE: Friday, Saturday, Sunday

The module is out of "Big Royal Mail". The relevant code seems to be:

So looks like the code initially determines if the module is active or inactive based on the admin setting (Which in this case will be date related), then if other criteria are "met" the module is deactivated, such as too large of a weight, etc... See below with the colored text based on the criteria provided for day of week. Including time would be possible as well.. There still is the "issue" of how it is desired to handle say someone initiating the purchase at 2359 on Thursday night, but not getting to the final purchase until 0000+ the next day. If it is considered acceptable to have the purchase started but not completed until after that midnight cutoff, then a $_SESSION[] variable could be used as a standin that would expire with logout/timeout...

Would like to take my nickel back a little... Basically the previous code enabled the module regardless of the setting in the admin panel, which is less than ideal... Below is a more correct version. Sorry about that.
