DateTime struct. Application programs can use this data structure to represent date and time values with large range and nanosecond precision.
tibDateTime values combine two numeric components.
- The
sec component represents whole seconds with up to 64 bits. Zero denotes the UNIX epoch – midnight entering January 1, 1970.
- The
nsec component represents nanoseconds after the time that the sec component denotes. Although the struct stores this component in a signed 64-bit integer, this component is always non-negative, between zero and 999999999.
For example, the value -1 seconds plus 999,999,998 nanoseconds represents December 31, 1969, 2 nanoseconds before midnight (that is, 2 nanoseconds before the epoch).
