This topic covers formatting options for dates, times, and numbers within LabKey Sample Manager.
Date and DateTime Format Strings
Format strings used to describe dates and date-times must be compatible with the format accepted by the Java class
SimpleDateFormat. For more information see the
Java documentation. The following table has a partial guide to pattern symbols.
Letter | Date/Time Component | Examples |
---|
G | Era designator | AD |
y | Year | 1996; 96 |
M | Month in year | July; Jul; 07 |
w | Week in year | 27 |
W | Week in month | 2 |
D | Day in year | 189 |
d | Day in month | 10 |
F | Day of week in month | 2 |
E | Day in week | Tuesday; Tue |
a | Am/pm marker | PM |
H | Hour in day (0-23) | 0 |
k | Hour in day (1-24) | 24 |
K | Hour in am/pm (0-11) | 0 |
h ....... | Hour in am/pm (1-12) ....... | 12 ....... |
m | Minute in hour | 30 |
s | Second in minute | 33 |
S | Millisecond | 978 |
z | Time Zone | Pacific Standard Time; PST; GMT-08:00 |
Z | Time Zone | -0800 |
X | Time Zone | -08; -0800; -08:00 |
Note that the LabKey date parser does not recognize time-only date strings. This means that you need to enter a full date string even when you wish to display time only. For example, you might enter a value of "2/2/09 4:00 PM" in order to display "04 PM" when using the format string "hh aa".
Number Format Strings
Format strings for Integer and Decimal fields must be compatible with the format that the java class
DecimalFormat accepts. A valid DecimalFormat is a pattern specifying a prefix, numeric part, and suffix. For more information see the
Java documentation. The following table has an abbreviated guide to pattern symbols:
Symbol | Location | Localized? | Meaning |
---|
0 | Number | Yes | Digit |
# | Number | Yes | Digit, zero shows as absent |
. | Number | Yes | Decimal separator or monetary decimal separator |
- | Number | Yes | Minus sign |
, | Number | Yes | Grouping separator |
Examples
The following examples apply to Date Type fields.
Format String | Display Result |
---|
yyyy-MM-dd HH:mm | 2008-05-17 01:45 |
yyyy-MM-dd HH:mmaa | 2008-05-17 01:45PM |
yyyy-MM-dd HH:mm:ss.SSS | 2008-05-17 01:45:55.127 |
MMMM dd yyyy | May 17 2008 |
hh:mmaa zzzz | 01:45PM Pacific Daylight Time |
The following examples apply to Decimal fields.
Format String | Display Result |
---|
<no string> | 85.0 |
0 | 85 |
000 | 085 |
.00 | 85.00 |
000.000 | 085.000 |
