Date and Time Formats
Year, Month, Day in Month — Time:
YYYY-MM-DDThh:mm:ss[.ssssss] ex. 1997-01-31T12:04:32.123
YYYY-MM-DD ex. 1997-01-31 a time of 00:00:00 is assumed
Where:
YYYY :: four-digit year MM :: two-digit month (01=January, etc.) DD :: two-digit day of month (01 through 31) T :: date-time separator hh :: two digits of hour (00 through 23) (AM/PM NOT allowed) mm :: two digits of minute (00 through 59) ss :: two digits of second (00 through 59) ssssss :: one to six digits representing decimal fractions of a second, down to microseconds
Glob Expressions
Wildcards
The question mark ? represents any single character (exactly one), while the asterisk * represents zero or more characters. These wildcards work when specifying a target, but not when specifying a SNCLQ filter.
