New! Dates Are Now Understood.#
It’s been too long since the last blog entry, and there’s good news to share. GF4 can now accept columns with dates, such as “2025-03-30”. The default format is year-month-day. The default can be set by editing the gf4.ini configuration file. The format string must follow the format used by python’s datetime library, which is pretty standard.
Dates are converted to decimal years: “2025-01-01” becomes 2025.0. Slashes can be ised instead of dashes for the year-month-day format, and if both conversions fail a few others are tried.
Dates can be used with versions of GF4 starting with V1.6, available in the “devel” branch of the repository..
