|
|
$$FMTH(x,y) |
To change a date from VA FileMan format to $H format.

y 1 (optional) to return the date portion only (no seconds)
|
|
$$HTE(x,y) |
To change a date in $H format to an external format
arguments: x $H date (in quotes)
y see FMTE(x,y) for alternate values
|
|
$$FMTE(x,y) |
To change a date in VA FileMan format to an external
format.
|
|
$$DOW(x,y) |
To change a date in VA FileMan format to the
corresponding day of the week.
|
|
$$HDIFF(x1,x2,x3) |
To calculate the difference between two dates in $H
format.
|
|
$$FMDIFF(x1,x2,x3) |
To calculate the difference between two dates in VA
FileMan format. x3 also serves as an argument
1, return difference in days
2, return difference in seconds
3, return difference in DD HH:MM:SS format
|
|
$$HADD(x,d,h,m,s) |
To add days, hours, minutes, and seconds to a date in
$H format (to x)
|
|
$$FMADD(x,d,h,m,s) |
To add days, hours, minutes, and seconds to a
date/time in VA FileMan format (to x).
|
|
$$DT |
Returns current date in FileMan format.
|
|
$$NOW |
Returns current date/time in FileMan format.
|
|
$$FMTHL7(fm_date/time) |
To change a date from VA FileMan format to HL7 format
including the time offset.
W $$FMTHL7^XLFDT(3001127.1525) => 200011271525-0800
|
|
$$HL7TFM(HL7 date/time[,Local/UTC]) |
To change a date from HL7 format to VA FileMan
format. W $$HL7TFM^XLFDT("200011271525-0700") => 3001127.1525
The optional second parameter controls if any time offset is applied to the
time. If a time offset is included then time offset can be applied to give UTC
time or the local time offset from the Mailman Time Zone file can be used to
give Local time.
To get UTC time W $$HL7TFM^XLFDT("200011271525-0700","U") => 3001127.2225
To get Local time in PST. W $$HL7TFM^XLFDT("200011271525-0700","L") =>
3001127.1425

$$SCH(schedule,lasttime,futureflag) |
This API decodes a schedule to give the next time in
the schedule. See the Kernel Library documentation for more detail on the
schedule string. The return value is a FileMan format date/time.

| VARIABLES |
TYPE |
VARIABLES DESCRIPTION |
schedule |
Input |
This is a string that describes the schedule. From
the Kernel Library Doc.
nS add n seconds to base_date
nH add n hours to base_date
nD add n days to base_date
nM add n months to base_date
$H;$H;$H List of $H dates
nM(list) complex month increment ie: 1M(15,L)
dd[@time] day of month ie: 12
nDay[@time] day of week in month ie: 1M
first monday

D = weekday
E = weekend
Day = M monday
T tuesday
W wednesday
R thursday
F friday
S saturday
U sunday
|
lasttime |
Input |
This is the last date/time (or base time) for the
schedule. The next date/time is figured from this point in time. It can be in
FileMan format e.g. 3011018.08 or in $H format e.g. 58730,28800.
|
futureflag |
Input |
This flag, if set to 1, will check that the returned
date/time is greater than the current date/time.
|
|
$$SEC(FM or $H value) |
This entry point will convert either a FM or $H value
to the number of seconds since the start for $H. W $$SEC^XLFDT(3021118.1347)
=>> 5108536020
|
|
$$%H(seconds) |
This entry point converts the output of $$SEC^XLFDT
back to a $H value.
W $$%H^XLFDT(5108536020) =>> 59126,49620
|
|
$$TZ() |
This entry point returns the Time Zone offset from
UTC.
For Pacific standard time: W $$TZ^XLFDT =>> -0800
|
|
$$FR(x) |
Checks x (FileMan date/time) is within the approved
range. Returns 0 if x is approved, 1 if x is out of range.
