General GUI description

The first General Options row contains checkboxes for some special behaviours, see Options below.

The second row is just the description of the fields shown in the third row.

The third Date | Time row contains input fields to specify a date/time. It also conatins the buttons and for converting from and to the Timestamp field shown as last input filed in this row.

The fourth human readable row contains a wide field for a common human readable date and time format, followed by the button which converts the value given there to the fields in the third row.
The buttons and convert the value to the timestamp Offset field shown last in this row.
There is also a button, which adds the value from the Offset field in this line to the Timestamp in the previous line.

The fifth row contains command buttons.

• The button simply gets the (browser's) current time and writes it to the fields in the third row. It also writes the date/time as human readable format in the fourth row.
  The computed time depends on the GMT option.
• The button resets all fields.
• The button tries to analyse the value from the input field in the fourth row and prints a list of possible matches.
• The button adds the value of the field to the scratchpad window.
• The button computes the Timestamp as sum of the Ref. Timestamp and the Offset.
• The button computes the Offset as difference from the Ref. Timestamp and the Timestamp.

Converting to/from timestamp (number of seconds)

The button converts the date/time given in the left fields to a timestamp in the right field.
The button converts the timestamp given in the right field to date/time in the left fields.
Both convertions also print the value in the human readable format.

Converting timestamp (number of seconds) from human readable format

The left input field in the human readable row can be used to convert from various formats to the date/time and timestamp in the third row. This is done by the button.
Following format are known:

• hh:mm (Note that just the hour and minute are usefull then)
• hh:mm:ss (Note that just the hour and minute are usefull then)
• hh:mm yyyy.mm.dd
• hh:mm:ss yyyy.mm.dd
• hh:mm:dd.mm.yyyy
• hh:mm dd.mm.yyyy
• hh:mm:ss dd.mm.yyyy
• yyyy.mm.dd
• yyyy.mm.dd hh-mm
• yyyy.mm.dd hh-mm-ss
• dd.mm.yyyy
• dd.mm.yyyy hh-mm
• dd.mm.yyyy hh-mm-ss

• .
• :
• /
• -
• ,
• (space)

Computing Offsets

The left input field in the fourth row can be used to compute an (timestamp) offset with the . Offset here means that it is the number of seconds from the specified date/time in the left input filed to the current time (which is same as we get by the button).
Note that this computation depends on the GMT and now options.

Options

• 2/4
  year are 2 rather than 4 digits
  Note that this results in ambigious values! and hence will always be assumed as yy/mm/dd in the range 1900 .. 1999.
• Name
  use names for months rather than numbers
• strict
  use strict matches for month (1..12), day (1..31), hour (1..23), minute and seconds (1..59)
  Note that there is no check if 29, 30 or 31 is a valid date for the specified month.
• now
  use current time if missing
• ms
  timestamp value in miliseconds
• GMT
  use GMT date and time
