int(0..59) System.TM.hour
int(1..31) System.TM.mday
int(0..11) System.TM.mon
int System.TM.year

Description

The various fields in the structure. Note that setting these might cause other fields to be recalculated, as an example, adding 1000 to the hour field would advance the 'mday', 'mon' and possibly 'year' fields.

When read the fields are always normalized.

Unlike the system struct tm the 'year' field is not year-1900, instead it is the actual year.

Variable yday

Description

The day of the year, from 0 (the first day) to 365 This is calculated from the other fields and can not be changed directly.
