There are two types of datetime values: absolute and relative. Absolute values specify exact dates and/or times. Relative values specify a span of time. Some examples will help clarify:
Absolute
The general format for absolute values is
day month year [bc] hour:minute:seconds timezone
day is 1-31
month is jan,feb,...,dec
year is 4 digit year
[bc] if present, indicates dates is BC
hour is 0-23 (24 hour clock)
mintue is 0-59
second is 0-59.9999 (fractions of second allowed)
timezone is +hhmm or -hhmm (eg, -0600)
parts can be missing
1994 [bc]
Jan 1994 [bc]
15 jan 1000 [bc]
15 jan 1994 [bc] 10 [+0000]
15 jan 1994 [bc] 10:00 [+0100]
15 jan 1994 [bc] 10:00:23.34 [-0500]
Relative
There are two types of relative datetime values, year-
month and day-second. The formats are:
[-] # years # months
[-] # days # hours # minutes # seconds
The words years, months, days, hours, minutes, seconds
are literal words, and the # are the numeric values.
Examples:
2 years
5 months
2 years 5 months
100 days
15 hours 25 minutes 35.34 seconds
100 days 25 minutes
1000 hours 35.34 seconds
The following are illegal because it mixes year-month and day-second (because the number of days in a month or in a year vary):
3 months 15 days
3 years 10 days
