• m/d/y h:m, m/d/y h:m:s, d/m/y h:m, d/m/y h:m:s, y/m/d h:m, y/m/d h:m:s,
ddMonyyyy h:m, ddMonyyyy h:m:s, ddMonyyyy:h:m, ddMonyyyy:h:m:s,
Monddyyyy h:m, Monddyyyy h:m:s show the number of hours, minutes, and seconds after
midnight of the prepended date. The date appears in the formats described above. The hours,
minutes, and seconds are separated by a colon. This example (12/31/2004) has no hours or
minutes. Examples of its formatted values with zero hours minutes and seconds are 12/31/
2004 12:00 AM and 12/31/2004 12:00:00 AM.
• :day:hr:m, :day:hr:m:s show the number of days, hours, minutes, and seconds since January
1, 1904. The results for December 31, 2004 are :36890:00:00: and :36890:00:00:00.
• h:m:s, d h:m gives hours, minutes, and seconds portion of the date in the date field. The
example used here (December 31, 2004) has no time entered, so the result is 00:00:00.
• yyyy-mm-ddThh:mm, yyyy-mm-ddThh:mm:ss show the year, month, day, and time. For
example, 2004-12-31T17:34:54. T is a literal, representing itself.
• Locale Date Time h:m and Locale Date Time h:m:s display a JMP time value according to
the settings of your operating system. For example, the local OS formats for time in the
United states are the formats mm/dd/yyyy hh:mm and mm/dd/yyyy hh:mm:ss.
