Macros

Type Name
define BUILD_DAY /* multi line expression */
Extracts the day from the __DATE__ string (e.g.: "Jul 22 2024" -> 22). Handles the case where the day has a single digit (e.g.: "Jul 7 2024").
define BUILD_HOUR ((\_\_TIME\_\_[0] - '0') \* 10 + (\_\_TIME\_\_[1] - '0'))
Extracts the hour from the __TIME__ string (e.g.: "18:30:00" -> 18).
define BUILD_MIN ((\_\_TIME\_\_[3] - '0') \* 10 + (\_\_TIME\_\_[4] - '0'))
Extracts the minute from the __TIME__ string (e.g.: "18:30:00" -> 30).
define BUILD_MONTH /* multi line expression */
Converts the text month to number (e.g.: "Jan" -> 1, "Feb" -> 2, etc).
define BUILD_SEC ((\_\_TIME\_\_[6] - '0') \* 10 + (\_\_TIME\_\_[7] - '0'))
Extracts the second from the __TIME__ string (e.g.: "18:30:00" -> 00).
define BUILD_YEAR /* multi line expression */
Extracts the year from the __DATE__ string (e.g.: "Jul 22 2024" -> 2024).
